Question

Force are acting on the boby from right side by 50n,the body is at rest the friction force is acting from
A)50n from right side.
B)50n from left side.
C)10n from right side.
D)10n from left side.

Answer 1

Answer:

Here is your answer plz mark me as a brainlest

B)50n from left side.

hope it's help you

Answer 2

If μ be the coefficient of friction, the friction force f=μmg

As friction opposes the motion, so the magnitude of friction force and appling force will be same here.

So, μmg=30 or μ= 50

30=0.6
