Question

Assertion The change in kinetic energy of a particle is equal to the work done on it by the net force.
Reason Change in kinetic energy of particle is equal to the work done only in case of a system of one particle.

• A. if both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
• B. if both Assertion and Reason are true but the Reason is nor the correct explanation of the Assertion
• C. if Assertion is true but Reason is false
• D. if Assertion and Reason are false

Answer 1

Answer: (C)
