(C) For an electric dipole consisting of charges $-q$ and $+q$ separated by a distance $2a$,the dipole moment $\vec{p}$ is directed from $-q$ to $+q$.$1$. On the axial line: The electric field $\vec{E}_{axis}$ at a point is in the same direction as the dipole moment $\vec{p}$.$2$. On the equatorial plane: The electric field $\vec{E}_{equator}$ at a point is in the direction opposite to the dipole moment $\vec{p}$.

Electric Dipole and Electric Field

An electric dipole with dipole moment $5 \times 10^{-6} \ Cm$ is aligned with the direction of a uniform electric field of magnitude $4 \times 10^5 \ N/C$. The dipole is then rotated through an angle of $60^{\circ}$ with respect to the electric field. The change in the potential energy of the dipole is (in $J$)
