A simple pendulum consists of a small sphere of mass m suspended by a thread of length l . the sphere carries a positive charge q . The pendulum is placed in a uniform electric field of strength E directed vertically upwards. With what period will the pendulum oscillate if the electrostatic force acting on the sphere is less than the gravitational force?

A simple pendulum consists of a small sphere of mass m suspended by a thread of length l . the sphere carries a positive charge q . The pendulum is placed in a uniform electric field of strength E directed vertically upwards. With what period will pendulum oscillate if the electrostatic force acting on the sphere is less than the gravitational force ?

A simple pendulum of mass m and charge +q is suspended vertically by a massless thread of length l. At the point of suspension, a point charge +q is also fixed. If the pendulum is displaced slightly from equilibrium position, its time period will be

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
