Question

A body of mass $6$ $kg$ has a force of $12$ $N$ acting on it parallel to the ground. (${\mu }_s=0.2$). If $g=10$ $m{s}^{-2}$, the body is in

• A. rest
• B. moving with uniform velocity
• C. accelerated motion
• D. we can not say

Answer 1

The correct option is A rest

Given,

$m=6kg$

${\mu }_s=0.2$

$F=12N$

Maximum static frictional force acting on the body$={\mu }_{s}mg=0.2\left(6\right)\left(10\right)=12N$
Since the static frictional force is equal to the force applied on the body, the body will be at rest.
