HW : w= mg= N 2×10 = 20 N=> Nf Coefficient of static friction(mu) =0.4 fs = (mu)s× N = 0.4 × 20 = 8 N But, even the 4N is acting on the object but the fsmax will cancel the force because it is Self Adjusting Force and the force is the less than fsmax ... 😊
Wrong, this is limiting force or f max so to move the block you need more than 8N force the force applied on the block is 4N since friction force is self adjusting it will adjust itself to 4N and cancel the force applied So the answer is 4N
Bro static friction (fs) is variable means it depends upon the applied force(F) but we know their will be a fs max of a body Let fs max = 10N and F = 8 N Since fs ( not fs max) is a variable force and is equal to applied force (F) Therefore, fs=8N i.e., 0
Solution is here Given Ms=0.4 Mass=2kg Applied force=4N Find force of friction Soln. N=W W=Mg =2x10=20 Msmax=MsxN =0.4x20 =8N Hence we need to produce more than 8N.but the Applied force is only 4N ,thus the object can not be moved.And answer for question =8N
In rolling friction 0.02*10N/1m means in the we get it's unit as N/M but frictional force unit is N how is it possible I want to understand and send me the details of the same to attend the class THANK YOU.
HW : w= mg= N
2×10 = 20 N=> Nf
Coefficient of static friction(mu) =0.4
fs = (mu)s× N
= 0.4 × 20
= 8 N
But, even the 4N is acting on the object but the fsmax will cancel the force because it is Self Adjusting Force and the force is the less than fsmax ... 😊
You are correct
👍👍👍
I think the answer would be 8N because--
M= 2 KG
W= mg
= 2 KG*10 m/s²
= 20N
Coefficient of static friction= 0.4
therefore, 0.4*20N= 8N
Wrong, this is limiting force or f max so to move the block you need more than 8N force the force applied on the block is 4N since friction force is self adjusting it will adjust itself to 4N and cancel the force applied
So the answer is 4N
Sir you explains very well with practicles
We are glad to have a 😊 such type of valuable classes by you sir
your the best teacher i have ever listened to
thanks for your helpful teaching
The frictional force is 8N.
Therefore the applied force, 4N, is not sufficient to move the box.
Thank you sir for clear explanation about friction ❤
You are welcome
Why we should not used cos theta instead of tan theta to calculate angle of friction. Sir
Same doubt
The way u taught ch friction now i don't have any doubt in this ch u r superb sirr thankyuu so muchh ❤
Hi,am benard from Uganda am happy to join you
Thanks Benard! Great to hear you like our videos! Do share it with your friends!

Bro static friction (fs) is variable means it depends upon the applied force(F) but we know their will be a fs max of a body
Let fs max = 10N
and F = 8 N
Since fs ( not fs max) is a variable force and is equal to applied force (F)
Therefore, fs=8N
i.e., 0

Glad it was helpful!
Nice way of teaching
Thanks for liking
Hi I'm Solomon Manyuot Mabor, from south Sudan am so glad for the work you have done ✅✅✅👍👍🎉🎉🎉.
Thanks. Glad it helped you
Fs max is proportionate to weight not normal btw
Sir can you please upload vectors addition and subtraction.
We will definitely try to upload more videos soon!

Great Video!!!
Thanks!
So wonderful topic
finally i get to understand this topic well
Your video is very helpful
Solution is here
Given
Ms=0.4
Mass=2kg
Applied force=4N
Find force of friction
Soln.
N=W
W=Mg
=2x10=20
Msmax=MsxN
=0.4x20
=8N
Hence we need to produce more than 8N.but the Applied force is only 4N ,thus the object can not be moved.And answer for question =8N

Well understand thank you sir 👏👏👏
Thank s sir ❤😊
Can you suggest me a good science book for class 8 and 9
Thanks a lot sir...ur way of explaining is inexpressible 🙏🙏.
Please bring courses for 11 and 12 sir 😭🙏
Your welcome! Courses for Class 11 are coming in the first week of January!
@@ManochaAcademy for 12 sir?
@@ManochaAcademy pls launch courses for 12 also🙏🙏😭
Sir can you please make a video on tension
Please can I get a video of calculation on this
Kinetic friction is also called as dynamic friction yes or no 🧐🧐🧐
In rolling friction 0.02 x10N/1m means in the final we get it's unit as N/m? But frictional force unit is N, how is it possible?
Hello sir thank you for explaining this topic i was trying to find this kind of vedio 😊
Sir, you are three much❤❤❤

Thanks Siddharth!
Is the answer 8N or 4N
Frictional force i.e the limiting friction is 8N
you are best sir
Sir is it 8N
The answer is 8n
Why are you not replying people that solve the problem 😢 so that we can know the answer
nice video
Thanks
Sir please make videos on ch electricity with experiments
5:06 hahah that sound
Nice friction😊
Very good sir
Thank you
Is it 8N
Well teaching
what is your name sir?
Before exam 😅
Thanks ☺️
Friction opposes motion, not the force.
I got 8N
Is it correct
Gud morning sir
Good morning
How are you sir 😊
