Question

Work done in the motion of a body over a closed loop is zero for every force in nature.

• A. True
• B. False

Answer 1

The correct option is B False

Explanation

1. Friction is not a conservative force
2. Hence work done by force of friction is not zero over a closed loop.
3. The work done during the motion of a body over a closed loop is zero only when body is moving under the action of a conservative force.

Hence, the statement is false.
