Physics · Electrostatic Potential

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In an external electric field \( \mathbf{E} \), the potential energy of a single point charge \( q \) is \( qV(\mathbf{r}) \), whereas that of an electric dipole \( \mathbf{p} \) is \( -\mathbf{p}\cdot\mathbf{E} \). Reason (R): An electric dipole experiences a net translational force in any non-zero electric field. In 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.
