Question

An electric dipole when placed in a uniform electric field will have minimum potential energy,if the angle between dipole moment and electric field is (A) zero (B) π/2 (C) π (D) 3π/2

Tardigrade Admin · Accepted Answer

The potential energy of a dipole in an electric field is, - vecp ⋅ vecE The potential energy is thus minimum when p and E are in the same direction.

zero

$π /2$

$π$

$3 π /2$

The potential energy of a dipole in an electric field is, $- p \cdot E$
The potential energy is thus minimum when $p$ and $E$ are in the same direction.

π/2

π

3π/2

The potential energy of a dipole in an electric field is, −p​⋅E The potential energy is thus minimum when p and E are in the same direction.
