Question

Attempt ANY ONE
A block of mass 2kg is kept on a horizontal surface. When a
horizontal force of 15 N is applied to it the block doesn't slide.
Calculate the coefficient of static friction
​

Answer 1

Explanation:

i think this is the answer......

Answer 2

Nice Question mate!!!

As the block doesn't move because of the applied force there are two possibilities either the force is less than limiting friction or equal to the limiting value.

Hence F ≤ μmg

          15 ≤ μ 2 x 20

           μ ≥ 3/4

Hope this helps !!!
