- Water easily holds a think needle on its surface by applying surface tension. The surface is the reason how does mosquito walk on water? Surface tension is the reason behind the water stays in drops on leaves. But how can we find the surface tension by water? In this video i have measured surface tension with a weighing scale. The needle is intensely pulled by the water surface by applying surface tension when we increase weight from other side. The moment needle leave the water surface, the weight becomes equal to the surface tension of water. Surface tension can also be measured by capillary action. #shorts #education #science #physics #facts @CONCEPTUALGURUJI

Great efforts and meaningful content thanks a lot keep it up sir
dekh kr boht afsoos hota ha k aisi videos Pakistan k log q nahi banaa rhy? hamesha Indians ki hi q samny aati hain aisi videos? huge respect from Pakistan
This is probably wrong method due to these points:
1) Force due to surface tension is not downwards it's tangential to the pin as pin is not linear, it's getting circular. Refer to second point for direction of force due to surface tension
2) Let the tangent makes angle ∆ with water surface so cos∆ components cancelled out and sin∆ component adds up in upwards direction, as ∆ is very small so sin∆=∆. So equilibrium equation becomes 2Tl∆=mg (m=mass of pin)
3) When you increase tension of thread you must be careful that it just lift up as on "just lift up" condition force due to surface tension vanishes and as it is just getting lifted so a=0 so Mg=mg (M=mass of sand, m=mass of pin)
So we got two equations
A) 2Tl∆=mg
B) Mg=mg
As M,l is known so
2Tl∆=Mg
But the problem is we don't know ∆.

@@manikmehta2727 I don't know Which is right and which is wrong. I am just impressed by the experiment, I think. This is right. Then it seems you are right seeing your science language. So who is right? People like me cannot decide. Those who consider things to be gold after seeing the shine.
But who will decide who is right and who is wrong? How to know which is right and which is wrong?
Aap ka videos bohot intresting or unique hota a or ya mujhe kii concept samajne ma madad bhi karte ha
Most of load is consumed to overcome friction at rotational joint
Oho... What an explanation....❤️❤️❤️❤️❤️
Surface tension neeche attract nhi karti bhai.. surface tension acts along the surface or interface of water. Jo neeche lag rahi hai wo net weight hai needle ki considering the buoyant forces
Correct this experiment is fake ,only true science students know
Aapka weighing scale frictionless (minimum friction) nahi hai!😅
Good explanation 👍
For the first time I understand surface tension for the first time
Yes
Maybe cohesive force act downward in surface tension
Your Great man...!!!🤩 Keep it up...i salute to your work✨
Surface tension acts in upward direction opposite to the weight of needle that's why it's floating but didn't you just put weight = wt. Of needle + adhesion force (b/w needle and water)- force of buoyancy.
And surface tension is different than that
Please correct me if i am wrong !
Ispe main detailed video bnaunga and then i can explain it in much better way🙏 koshis krunga ki sbhi questions k answer kr sku usme..thanks for ur concern btw🙏❤️thanks for ur love and support🙏❤️
Wow .. interesting ✌️
Excellent idea,
But there are many factors which influence your weight balance or equilibrium of your scale,
Surface tension Aaj samajh aaya...
man .... u r doing awesome work... keep up .. we are with you
Great video this call real physics
It has a slight problem that when you drop the suger or anything else on the paper, it falls down with a little amount of speed and this speed makes it heavier than before for just a very few time. That's the case of momentum.
I know how to fix this problem. But, I want you to fix it. Keep thinking. Thinking is the source of solution‼️🙏🏼🙏🏼
Jo weight of sugar aaya hai vo mg of needle + surface tension force ke equal hoga na ki only surface tension ke
Few questions
1) Is your String massless?
2) is your balance frictionless?
3)what about needle weight?
Few answer
Massless string possible bhi
Frictionless possible nhi
Vo koi avg needle weight jitna hoga
Or bhai ye frictionless and massless real life mae todi hota hae 🙂
Amazing explanation 🎉
No bro,Surface tension calculate karne keleye jo aya hain last may usme se Mg minus karna padega
Surface tension upward direction me kam krta hai jo niddle ka weight ko balance kr rha hoga...
Aapne jo measure Kiya hai jo water or niddle ke bich ka adhesive force hai...
Wow nice concept🙂🙂
Great job sir plss make more videos
Wow nice explain
But you balancing both surface tension and weight of the needle by the applying force through that pouch which mean the force on which needle come out is the force that is equal to both weight of needle + surface tension.
Finally good content on Ytube shorts
Wow nice explanation
Buhat alaaa , buhat barhya
Mast experiment he par Muze lagta he ki
Ts = weight on other side - weight of needle
Aisa hoga kyuki sirface tesion ke sath sath gravity bhi needle ko niche khichegi 🤔
Not sure about water, I studied somewhere k pani k ooper gravity apply nahii hotii.. not sure. There is another point in it, wo ye k jo scale (ice-cream ki sastii stick) lgaaya hai uskii friction b matter kry gii.😁
@@ZeeshanAhmed-os6bwPani mai buoyant force lagta hai jo gravity ko oppose karta hai but Iskandar Matlab yeh nhi ki Pani mai gravitational force nhi lagra
Surface tension= ( weight of sugar - weight of needle )/2
Agar aap nidel ko kisi leaf ke upar rakh kar phir pani dalo or dirhe se leaf ko niche dubba do to bhi nidel float karegi pls check it 😉😉
Wish we had some teacher explained this way instead of just understanding theory based articles.
U have to subtract needle's weight from it i think 🤔😅
Actually i have balanced the weight of needle in starting and then placed the needle on the water without slacking the thread that’s why needle weight never comes in consideration here😅 btw thanks for ur love and support🙏❤️
Does the elasticity of the string has any effect on ur calculated value ? Did u compare ur value with water surface tension already mentioned n books
@@CONCEPTUALGURUJI
@@sciencefun7247 there are many end corrections i can see but they are very negligible
Incredible thinking keep it up
Brilliant idea to measure
It's not simple as you have show here, We also need to consider angle oof contact btwn needle and water surface. Then Need to write force equilibrium
Best way of teaching keep it up bro
Bro ek number... Unique.
Muje lagta hai water k surface tension se zyada weight scale k bich k friction ki wajah se atka hua hai.
BTW Thankyou sir. Really meaningful video.
Faded short video lagra Raha hey gayab hone ka samay agaya.thanks❤
GOOD IMAGINATION TO CONVINCE
Niddle is floating on water surface due to surface tension but don't move upward even after applied load due to adhesive force between needle and water not due to surface tension surface tension helping only not to move needle inside water
After a hell lot of a absurd videos, finally I found something that I can like and I liked it 👍
It will be 2TS=mg
Not ts=mg
As 2 layers will be formed...
Brilliant explanation
I literally respect your efforts but bhai aapne linear tension ko surface tension se equate kr diya jabki both are two distinct things. Surface tension me needle ki length ka multiplication krne se vo weight wale tension ke equal banega. Aapne concept galat padha diya. But I still commend your efforts. 👍
Actually aap sahi bol rhe ho maine ek detailed video banauga usme puri calculations dikhaunga…i have jst shown a technique to find out the surface tension..btw thanks for ur concern🙏and thanks for ur love and support❤️🙏
Wow!!!
Just genius bro.
Aw 😮wow
Can you try the same experiment with round container like lota instead of flat container...
😌Nice sir🤟
Needle ka mass bhi consider karna padega na, and surface tension is not a force.. Use weight se equate nhi kar sakte
Needle jst surface ko touch kr rha h aur uska weight already barabar h dusre side se water k surface ko touch krne se phle..surface tension is force per unit length on the body so weight equate kraenge pure needle k length pr lgne wale force ke..i hope aapko smjh aa gya hoga and really thanks for the concern🙏and thanks for love and support sir❤️🙏
Bhai yaha kuchh specifications toh do yaha apne nidle water me dala or suface tension nikal liya but jab hum jyada area cover krne Bali cheej ko pani me dalenge tb phir tumhara surface tension increase ho jayega so give us fully content able information.
Unique Experiment
Not measuring surface tension but
Measuring adhesive force between needle and water
Simply it's a mechanical transducer.....
👍
Appreciate your work... But surface tension is not in downwards direction!!!
this principles use in Civil work for bridge or sub base road Called plate bearing test 😊
Great efforts but i have a doubt
Surface trnsion is because of the cohesion properties of water but this is working because of the adhesion property
If cohesive forces are less then adhesive property then this may give accurate results.
But if adhesive forces are weaker it may break before actual limit of cohesive forces
Nice experiment sir
Good way to show surface tension but it is not equal to weight
Ek bahut Badi barometer banao jo hazaron watt energy forever deta rahega
Please try with "salt water", if you try please 'DM' me...🙏 Very good video 👏👏👏👏
Are you sure ? Inward pressure and outward pressure is same ? Adhesive force and tension force is same ?
I need it more.
U forgot to include friction co efficient at the fulcrum
Sir,surface tension is because of cohesion but force on needle is adhesive force
Isn't mg also acting with surface tension in the needle ??
Best explanation ♥️
Check surface tension in indian Lota vs glass plz
great work
Consider weight of needle too and -ve gravity acting on it .
Nice 😮
Wao!
जल का भार उसके पृष्ठ तनाव में से भी तो - पड़ेगा भाई
Better than so called biral bideo 🤡🤡 warna baaki sab toh sirf centre of mass ka chutiyap karte hai 2nd standard wala experiment you explained very well man kudos to you 😍😍
Paper weight - niddile weight+ sugar weight= surface tension
Papa- beta itne kam marks kaise aae exam me
Beta- Papa mujhe bohot surface tension hai isliye Kam aae
😂😂
Great explanation
Absolute worth
Waaow
Simply we can find the magnitude 9f upthrust , right?
And that is why force needed to lift the needle = 2× surfce tension× length of needle
Very nice juagad experiment
Commerce Students: Mai Iska Apni Life me Kya krun 😂😂
Btw Nice explanation ♥️
Searls torsion balance method to find out surface tension
I think you should include gravity apply on the needle , mean weight of needle
(Maass of sugar ×g) = 2sl + (Mass of needle x g )
Here S is surface tension
That's the adhesive nature of property (in ascent of sap, adhesive n cohesive can be studied)
I think direction of surface tension is along surface and perpendicular to needle then how surface tension acts in downward direction?? Plz correct me if i am wrong
It's perpendicular to the needle 🗿
Nice experiment
No friction less pulley, not the best thread = errors
Good 👍
Very noice ✌🏻
