Question

A person applies a force of 200N to move an object initially at rest weighing 400N. What could be the coefficient of static friction between the object and the surface?

Answer 1

Answer:

$\mu=0.5$

Explanation:

Given that,

Applied force, F = 200 N

Weight of the object, or the normal force, N = 400 N

We need to find the coefficient of static friction between the object and the surface.

The force of friction has the same magnitude as that of applied force. It can be given by :

$F=\mu mg$

mg is weight of the object

$\mu=\dfrac{F}{mg}\\\\\mu=\dfrac{200}{400}\\\\\mu=0.5$

So, the coefficient of static friction between the object and the surface is 0.5.
