Physics · Electrostatic Potential

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The work done by an electrostatic field in moving a charge from one point to another depends only on the initial and final points and is independent of the path taken. Reason (R): Electrostatic force is a conservative force, and the concept of potential energy is valid only for conservative forces. 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.
