A simple pendulum having caharge ` q_1` mass ma and effective length `1`, is suspended from a rigid support between the plates of charged horizontal capacitor. Electric field in the capacitor is perpendicular to the plates and directed vertically downwards .

The time period of socillattion of the pendulum is given by :

A

` T= 2 pi sqrt ( l/(sqrt (g^2 + ((qE)/m)^2))`

B

` T= 2 pi sqrt ( l/(sqrt (g^2 + ((qE)/m)^2))`

C

` T= 2 pi sqrt ( l/(g^2 + (qE)/m)`

D
