Physics · WORK, ENERGY AND POWER

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The absolute value of potential energy of a physical system at a given point has no unique physical significance; only differences in potential energy are physically meaningful. Reason (R): The point chosen as the zero reference level of potential energy is arbitrary. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
