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 angle ` alpha` between the equilibrium position of the pendulum and the vertical is given by.A. ` alpha = sin^(-1) [ ((qQE//m)sin theta)/(h + (qE//m) vod theta) ]`B. ` alpha = cos ^(-1) [ ((qQE//m)sin theta)/(h + (qE//m) vod theta) ]`C. ` alpha = tan^(-1) [ ((qQE//m)sin theta)/(h + (qE//m) vod theta) ]`D. ` alpha = cos ^(-1) [ ((qQE//m)sin theta)/(h + (qE//m) vod theta) ]` |
