Assertion : Net external force acting on a system of particles is zero but it possible that kinetic energy of the system increases .
Reason : Kinetic energy of the system can be changed by internal forces of the system .

A

If both assertion and reason are corret and reason is a correct explanation of the assertion .

B

If both assertion and reason are correct but reason is ot the correct explanation of assertion .

C

If assertion is correct but reason is incorrect .

D

If both assertion and reason are incorrect .

Text Solution

Verified by Experts

The correct Answer is:
A
Take an example of two oppositely charged particles released from state of rest at some distance . Electrostatic force state of rest at some distance . Electrostatic force of attraction becomes internal force if we consider both the particles in our system .
