Problem

An electric dipole with moment

p = 4 \times 10^{-9}\,\text{C}\,\text{m}

is aligned parallel to a uniform electric field of magnitude

E = 5 \times 10^{4}\,\text{N/C}

. Calculate the amount of work done by an external agent to rotate the dipole by

60^{\circ}

from its initial stable equilibrium position.
