For a body on a horizontal surface, coefficients of static and kinetic frictions are 0.4 and 0.2 respectively. When the body is in uniform motion on the surface, a horizontal force equal in magnitude to limiting friction is applied on it. The acceleration produced is

A

0.4g

B

0.1 g

C

0.2 g

D

0.6 g

Text Solution

Verified by Experts

The correct Answer is:
c
`a = (mu_(s) - mu_(k)) mg//m = (0.4 - 0.2) = 0.2` g
