Potential energy of an electric dipole is minimum (Negatively maximum) when .........

Options

A. The dipole is perpendicular to the field
B. The dipole is parallel to the field
C. The dipole is antiparallel to the field.
D. The dipole moment makes `60^(@)` with the field.

Answer

A, B, C, D

Explanation

`U =- vecE.vecP=- E p cos theta`
If `theta=0 implies U = - Eo ` it is negative so minimum.
