Question

2 Based on Fundamentals of Friction What is the minimum force that needs to be applied on a body of mass 100 g, kept on a horizontal surface, to set the body in motion? Given, coefficient of friction between the surface and the body is 0.4 and the force acts parallel to the surface. (39200 dyn]​

Answer 1

Explanation:

block is placed on the horizontal plane, so mg=N

also maximum friction force is μ.N, which is 0.8 N.

friction force will be equal to force applied until it reaches its maximum value. After that limiting friction will act and body will start moving.

so μ.N=98=>μ.×0.1×10=0.8

=>μ=0.8
