NEET Physics Question - Work Energy and Power - Work Done by Constant and Variable Forces

Assertion (A): The work done during a round trip is always zero.

Reason (R): No force is required to move a body in its round trip.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Work done by conservative forces in a closed loop is zero. For all forces, it depends on energy change and non-conservative forces. Force is required to move a body, especially to overcome inertia or friction. Therefore, both Assertion (A) and Reason (R) are false.
