Question

A block of mass m is kept on a horizontal table. If the static friction coefficient is $\mu mg$ frictional force acting on the block

• A. 0
• B. $\mu mg$
• C. $2\mu mg$
• D. $\mu \mathrm{mg}2$

Answer 1

The correct option is A 0

By definition , frictional Force resists the force which drives a body into motion,

Frictional force acts as per the requirement to stop a motion,
with a maximum value of $\mu N$

Here the body is at rest,

Hence , no friction needs to be acting to resist any motion.

Option $\text{A}$ is the correct answer
