Physics Work, Energy, Power and Collision Assertion & Reason MCQ (Single Correct)

In this question, a statement of assertion is followed by a statement of reason . Mark the correct choice as:

Assertion: A light body and heavy body have same momentum. Then they also have same kinetic energy.

Reason: Kinetic energy depends on mass of the body.

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

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct answer is:

Kinetic energy of a body of mass

Again, Kinetic energy of a body of mass

As given,
Therefore, , i.e. the kinetic energy of light body will be more than the kinetic energy of heavy body when both have same momentum.
