Question

Assertion (A): A body capable of doing work is said to possess energy.

Reason (R): There is a transfer of energy if a body is acted upon by a force normal to the direction of displacement.

विकल्प

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correction explanation of Assertion.

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Assertion (A) is true, but Reason (R) is false.

Explanation:

The assertion is true because energy is defined as the capacity of a body to do work. The reason is false because a force perpendicular (normal) to the displacement does zero work (cos 90° =  0), meaning it cannot transfer any energy to the body through that work.
