Physics · JEE | Electrostatic Potential and Capacitance

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): The potential energy of a system of like charges is positive.\n Reason (R): Positive work must be done by an external force to bring like charges from infinity to a finite separation against their mutual repulsion. \nIn the light of the above statements, choose the correct answer from the options given below:

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