Question

A block of mass 2kg which is placed on a horizontal surface is pulled by a horizontal force of 50N. What maximum coefficient of static friction is required?

gravity=10m/s2​

Answer 1

The maximum coefficient of static friction required to pull the box will be 0.4.

Step-by-step explanation:

We have given a box of mass 2 kg and Force of 50 N. (g=10m/s)

As we know,

Coefficient of static friction: μ = F/N (I)(F=ma, a= g)

Putting value in equation (I), we get

μ= mg/

μ=2×10/50

μ=0.4
