One of the forces acting on the particle is conservative, then

A

(a) Its work is zero when the particle moves exactly once around any closed path.

B

(b) Its work equals the change in the kinetic energy of the particle.

C

(c) It does not obey Newton's second law.

D

(d) Its work depends on the end points of the motion, not on the path in between.

Text Solution

Verified by Experts

The correct Answer is:
A, D
It is the defination of a conservative force. Increase in KE will be due to work done by other forces also.
