A body of mass 2 kg is placed on a horizontal surface having kinetic friction 0.4 and static friction 0.5. If the force applied on the body is 2.5 N, then the frictional force acting on the body will be

A

8N

B

10 N

C

20 N

D

2.5 N

Text Solution

Verified by Experts

The correct Answer is:
d
`f_(k)=0.4 xx 2 xx 10 N =8 N`
`f_(ms)=0.5 xx 2 xx 10N= 10 N`
Since the applied force is less than force of friction, therefore the force of friction is equal to the applied force i.e.,2.5 N.
