Physics · Electrostatic Potential
हिन्दीGiven 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:
Correct answer · Option 3
(A) is true but (R) is false.
Explanation
Assertion is true. Reason is false because in a uniform electric field, the net translational force on a dipole is zero (F_net = qE - qE = 0).
