A simple pendulum has a length `l` & mass of bob m. The bob is given a charge q coulomb. The pendulum is suspended in a uniform horizontal electric field of strength E as shown in figure, then calculate the time period of oscillation when bob is slightly displaced from its mean position.

A

`2pisqrt(l/g)`

B

`2pisqrt({l/(g+(qE)/(m))})`

C

`2pisqrt({l/(g-(qE)/(m))})`

D

`2pisqrt(l/sqrt(g^2+((qE)/(m))))`
