A body of weight 50 N is placed on a smooth surface. If the force required to move the body on the rough surface is 30 N the coefficient of friction is

A

0.6

B

1.2

C

0.3

D

1.67

Text Solution

Verified by Experts

The correct Answer is:
A
Coefficient of friction, `mu = f/r`
Weight of the body, R = 50 N
Force, F = 30 N
`mu=30/50=0.6`
