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