- In this Chemistry video in Hindi for class 11 we explained the Millikan's oil drop experiment which was conducted by Robert Millikan and Harvey Fletcher. They found that the of an electron is -1.59 X 10 ^ (-19) coulomb which is very close to todays accepted value for the charge of an electron. Millikan and Fletcher computed the charge by measuring the terminal velocity of oil droplets.

sir me science ka divana hu. me abhi 11th me hu aur scintest banna chahth hu. apne mera oil dro experiment ka concept clear kardiya. thankyou very much.......
Wah same here..Me bhi astronomers bnna chahta hu ISRO me😋..Best of luck 🤗
Pdho bcho pdho 🤣🤣😂 abhi science ko tmne dekha hi kaha h
Me too😊
Best of luck to you all.

It is very difficult to find such a teacher like you nowadays specially in India where teachers of chemistry only teaches which comes in exam(jee or neet) and the irony is that the concepts which comes in exam they also don't know anything about that concept, they only have done so much practise that they can only teach students how to solve exam questions😔😔
Hats off to you sir You teach pure depth of science ♥️♥️♥️♥️
thanks sir..... thank you very much.... this topic was very hard for me.. as no teachers or youtube videos could solve my confusion....bt your video removed all diffficulties.... thanks.....
Thank you please continue rakhiye 11th and 12th ke videos outstanding videos of your physics .
Hello Dr. Lakshay garg,

“In the objective system of units CGS (cm, g, s), k was taken as a dimensionless unit, k = 1, which led to the absurd dimension of the charge q, expressed in fractional powers in units of length and mass ([q] = g1/2 cm 3/2 s-1). "

Best explaination sir 👍👍Thank You very much....
Best channel on YT
Sir aap bta skte hai aapne isko without using instruments kaise kiya h
Because aajkal clg bnd hai hai or sir ne bola h ki aapne isse laptop ya computer pe krna h nd I don't know mai apne laptop me kon sa software install kru
Thank you so much sir it helped me a lot
Best explanation sir Thankyou very much
Awesome. Thanks 😊
Excellently explained sir ❣️ Thank you very much 🙏🏻😊
His video,audio,explaination all are awesome
Thank u sir you helped me alot
Sir
While calculating buoyant force, which density did we actually take?
For Eg, in the case of gravitational force, you took the density of oil particle. But did you take the same density in case of buoyant force???
Buoyant force is equal to the weight of the fluid displaced. Here fluid is air. So weight of the fluid displaced = mass×g
Mass = density × volume
Since we are talking about fluid that is air, we will take density of air
And volume? Of the drop because that much volume of air is taken by the drop, clear?
@@zainasiddiqui5257 but....why did he written volume of air displaced as 4/3πr³.
@@adarshjena407because volume of air displaced is equal to volume of oil drop
Oil drop is in sphere form and formula for volume of sphere is 4/3πr³
Clear? 😊
Perfectly explained
Sir....who container kis material s bna hua tha....
Hats Off 🙌🙌🙌🙌
If the plates were not connecting how will the circuit complete and plate become charged ? And why ionizing is important becz due to voltage gas already became a conductor.......
Thanks sir for clear my douts 🤗🤗
Sir beyond force tou pani m lgega tou iss experiment m pani tou h hi ni tou byond force q lgega
Sir , this is little bit tough to me due to some new therms.So,can you please make another video that can help me to understand these new terms like viscous force and it's relation with g.
What does it mean by 1.602×10^-19 coulomb?! Please tell me!!
Ye value proton ka charge hai
1.602×^-19 coloumb
,Aur agar ye value negative hai matlab -1.602 ×10^-19 to ye electron ka charge hota
Thanks and keep it up 👍👍😊😊
Thank you very much sir for this beautiful explanation of the experiment...I would like to remind you about silly mistake that in derivation part in second statement it should be Fv1 = Fg -Fb.....however it was corrected by you in next statement....also sir please explain about how at last eta's value was changed and it changed the overall value of q in derivation.
Thank you sir..😊😊
Excellent video
Thanks sir
This is too good
Very very very nice 👍👍
Thank you sir 🙏😊
Best Teacher
absolutely amazing😊
Thanks sir, in book this was given in very short, I was not able to understand, thank you for explanation
Thanq sir 🙏🙏🙏🙏🙏🙏
Hello sir I found it excellent but I have a doubt In a equation i.e; q how do we get n in cube I think it should be square
If some numbers n1,n2,n3,.... are integral multiples of some number c, won't they be multiples of c/t, where t is an integer. Consider an example. 8,12,16 are multiples of 4, but they are also multiples of 2, which is 4 over an integer (in this case 2 itself) how did they know this is the value, as according to this those multiples must also have been multiples of half of the charge of an electron, one third of the charge and so on
Excellent sir ji🙏🙏🙏👍👍👍👍❤️❤️❤️
nd . sir keep uploading all the possible videos of class 11
Nice teaching 👌👌👌
thank you so much sir ji
Sir last mai n se n3 kaise ho gya clip mai jo bataye the
Ye ek aisa channel hai jaha pr aache accho ko physics se pyaar ho jaaega.
Sir chemistry ke students ko in experiments ko epth me samajhne ke liye konse topics padhne chahiye phhsics ???taki unhe kisi bhi chiz ko ratna na pade
U can refer Tata textbooks or oxfords textbook
Very helpful
Thanq sir
sir, Clip main jo equations solve ki gayi hai usme second line main misprint hai
Ok.
Let me see.
And ... thank you very much for your valuable comment.
Sir Physics Olympiad pe series banaiye please
Sir if the force of gravity is equal to the force of byoncy and viscosity,then why the oil drop had not gone to rest??
Because force is zero means there is no acceleration but there will always be velocity(terminal velocity)
Plz anss Hi ,sir but why buyont force here as where is liquid here??? Plz answer I want to know
Byocant force is not only for liquid
It is for fluid and both water and air are fluid😊
Sir pls make more videos 👍
Nice sir maja aa gaya
nice video thanks
Absolutely amazing explanation..👍🙏. Thanks.
Super sir🙏🙏
Thanks
Thanks 🙏

काश स्कूल में भी ऐसे teachers होते
Sir,ek question hai ki oil drop me to electron ke sath proton bhi hoga phir Kewal electron ki value kaise aayi
Bhai proton is attracted by other protons and neutron know as nuclear force. They together form a heavy mass called nucleus. Beside electron is free and less energy requide to remove from its orbit, hence electron stick on the oil.
Solid sir explained in amazing way
Great channel.... Luv ur way of teaching....
Nice sir
Sir drag force par ek video bana do pleace
Thank you so much sir. YOURS VIDEOS ARE VERY HELPFUL TO ME IN MY PREPARATAION. ALTHOUGH I AM IN 11th standard right now but I am preparing for completion.😅😅😅😅
Completion 😂😂
Tq sir
Fine
Wonderful video, thank you sir
Good
Sir why carbon atom forms long chain
💩
good
Why do we use oil in automizer instead of any other liquid????
I think bcoz milikan like oil instead of any other things 😂😂😂
@@sayashtripathi5062 lol 😂
Bcoz oil is more viscous
@@nightstoriesfromhell how can you justify your answer..... Means what role does viscosity play in this experiment?
@@nightstoriesfromhell Non Volatile too
As a 11th grade student I wanna ask that is this calculation important for me to understand or I just need to understand the conclusion?
Conclusion
Sir ek doubt h, why was only oil drop used why not water
Because oil drop easily ionized due to friction
love from nepal
What's a vedio😍🤩
Your spelling is wrong
You are great sir,...and special thanks
Informative.thanks sir.💗
Thnxx for this video I want to study deep about oil drop method
Nice
One of the nicest vedio......👏👏👏
Mind-blowing actually ,,,🙏

Sir if the net force is zero....then how is a constant velocity acting on the oil drop in downward direction...it should stop right?...someone please explain🙏🙏🙏
See, buoyant force and viscous force are acting in upward direction and acceleration due to gravity (g)is acting in downward direction. If upper and down force are same, net force is 0 bcz both upper and lower force cut each other.and oil drop is going in down due and up also.due to constant velocity net force is 0. I think so.
Due to electric field oil drop is going up and due to g it goes down.
I hv same doubt
Its like this
Since the net force is zero
The acceleration of the oil is also 0
And newtons 1st law says "with net force 0,the body's velocity will have same magnitude and same direction"
i.e body requires unbalanced force for change in velocity or even to make it zero.Since force is balanced , the body moves with the same velocity attained at that point when force gets balanced and velocity becomes constant.
Mst
Thank you so much sir🙏
Sr isme fe =Eq kaise ho gya or even Eq matlab
Sir i have been wathing your video for a long.Sir how electrostatic force acts on the oil drop whereas it is neutral
Thank you sir for the video🙏🏻🙏🏻
There are some chapters incomolete or missing sir plzz upload them too...
Sir, I am watching your whole series. 🙏🙂😱🤐🙂
Wahhhh bhtt shaandar.....bhtt
Bhtt shukriya janab😃❣❣❣❣

Nhi samaj aa raha
Why did millikon use oil instead of water..
Water gets vaporized easily
Sir aap ek din àisa lecture kariyega jisme ki har ek cheez aur uska unit bataiyega
❤
sir I m in class9th. i read millikan oil drop experiment.
Thank you for this video 🙏🙏🙏❤️❤️❤️
Sir , which oil was used in this experiment?
