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

Answer»

<P>The dipole is PERPENDICULAR to the field
The dipole is parallel to the field
The dipole is antiparallel to the field.
The dipole moment makes `60^(@)` with the field.

Solution :`U =- vecE.vecP=- E p COS theta`
If `theta=0 IMPLIES U = - Eo ` it is negative so minimum.
