1. Electric Charges and Fields
normal
An electric dipole is situated in an electric field of uniform intensity $E$ whose dipole moment is $p$ and moment of inertia is $I$. If the dipole is displaced slightly from the equilibrium position, then the angular frequency of its oscillations is
A
${\left( {\frac{{pE}}{I}} \right)^{1/2}}$
B
${\left( {\frac{{pE}}{I}} \right)^{3/2}}$
C
${\left( {\frac{I}{{pE}}} \right)^{1/2}}$
D
${\left( {\frac{p}{{IE}}} \right)^{1/2}}$
Solution
$\mathrm{T}=2 \pi \sqrt{\frac{\mathrm{I}}{\mathrm{PE}}}$
$\mathrm{w}=\left(\frac{\mathrm{pE}}{\mathrm{I}}\right)^{1 / 2}$
