A dipole comprises of two charged particles of identical magnitude

q

and opposite in nature. The mass 'm' of the positive charged particle is half of the mass of the negative charged particle. The two charges are separated by a distance '

l

'. If the dipole is placed in a uniform electric field '

\bar{E}

'; in such a way that dipole axis makes a very small angle with the electric field, '

\bar{E}

'. The angular frequency of the oscillations of the dipole when released is given by:

A
$\sqrt{\frac{3 q E}{2 m l}}$
B
$\sqrt{\frac{4 q E}{m l}}$
C
$\sqrt{\frac{8 q E}{3 m l}}$
D
$\sqrt{\frac{8 q E}{m l}}$
