Question

When a moving body is suddenly stopped, then:
  1. Frictional force increases.
  2. Friction force remains same as it was while the car was moving.
  3. Friction force reduces but has a non zero value.
  4. Frictional force reduces to zero as it is a self adjusting force.

A
Frictional force increases.
B
Frictional force reduces to zero as it is a self adjusting force.
C
Friction force remains same as it was while the car was moving.
D
Friction force reduces but has a non zero value.
Solution
Verified by Toppr

Frictional force arises when there is a relative motion between two surfaces. When body is stopped means there is no relative motion and no resultant force is there hence frictional force acting becomes zero.
