Write the formulas for the electric field due to an electric dipole and the magnetic field due to a current-carrying loop at a point on their respective equatorial (bisector) lines at a distance $x$.
(N/A) The electric field $\overrightarrow{E}$ due to an electric dipole with dipole moment $\overrightarrow{p_{e}}$ at a point on its equatorial line at a distance $x$ (where $x >> a$) is given by:
$\overrightarrow{E} = -\frac{\overrightarrow{p_{e}}}{4 \pi \epsilon_{0} x^{3}}$
The magnetic field $\overrightarrow{B}$ due to a current-carrying loop with magnetic moment $\overrightarrow{m}$ at a point on its axis at a distance $x$ (where $x >> R$) is given by:
$\overrightarrow{B} = \frac{\mu_{0}}{4 \pi} \frac{2\overrightarrow{m}}{x^{3}}$
Note: The equatorial field for a dipole is antiparallel to the dipole moment,while the axial field for a magnetic loop is parallel to the magnetic moment.

An electric dipole of moment $\vec{P}$ is placed in a uniform electric field $\vec{E}$ such that $\vec{P}$ points along $\vec{E}$. If the dipole is slightly rotated about an axis perpendicular to the plane containing $\vec{E}$ and $\vec{P}$ and passing through the centre of the dipole, the dipole executes simple harmonic motion. Consider $I$ to be the moment of inertia of the dipole about the axis of rotation. What is the time period of such oscillation?
