NEET Physics Question - Work Energy and Power - Potential Energy & Equilibrium

Assertion (A): The work done by a non-conservative force is always negative.

Reason (R): When a non-conservative force is involved in a system, it always dissipates energy.

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

Work done by non-conservative forces can be positive (e.g., applied force) or negative (e.g., friction), so (A) is false.

Non-conservative forces can dissipate (friction) or add (engine thrust) energy. So (R) is also false.
