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 in bringing a test charge \( q \) from infinity to a point inside an external field is independent of the path taken. Reason (R): The electrostatic field is a conservative force field. 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.
