Problem

An electric dipole is formed by two equal and opposite charges

q

with separation

d

. The charges have same mass

m

. It is kept in a uniform electric field

E

. If it is slightly rotated from its equilibrium orientation, then its angular frequency

\omega

is : a.

\sqrt{\frac{qE}{md}}

\sqrt{\frac{2qE}{md}}

2\sqrt{\frac{qE}{md}}

\sqrt{\frac{qE}{2md}}
