A simple pendulum of length L is placed between the plates of a parallel plate capacitor having electric field E, as shown in figure. Its bob has mass m and charge q. The time period of the pendulum is given by:

A neutral pendulum oscillates in a uniform electric field as shown in figure. If a positive charge is given to the pendulum, then its time period

How will the electric field between the plates in parallel plate capacitor change, if the charge on the plates is doubled?

A small metallic bob of mass m of a simple pendulum of length L is suspended between the two oppositely charged large parallel plates . The electric field E act vertically. If positive charge 'q' is given to bob and displaced slightly from mean position then time period of oscillation will be

A small metallic bob of mass m of a simple pendulum of length l is suspended from a silk threas between two parallel charged plates.The electric field intensity E act vertically downwards . If bob is given a charge + q ,time period of oscillation (i) T = 2 pi sqrt((l)/((g - (qE)/(m)))) , if the lower plate is charged positively (ii) T = 2 pi sqrt((l)/((g - (qE)/(m)))) ,if the lower plate is charged negatively (iii) T = 2 pi sqrt((l)/((g + (qE)/(m)))) ,if the lower plate is charged positively (iv) T = 2 pi sqrt((l)/((g + (qE)/(m)))) , if the lower plate is charged negatively
