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 simple pendulum has a length l , mass of bob m . The bob is given a charge q .The pendulum is suspended between the vertical plates of charged parallel plate capacitor. If E is the field strength between the plates ,then time period T =

A simple pendulum oscillates slightly above a large horizontal metal plate. The bob is given a charge. The time period

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

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 has time period T The bob is given negative charge and surface below it is given position change new time period will be

A pendulum bob of mass m charge q is at rest with its string making an angle theta with the vertical in a uniform horizontal electric field E. The tension in the string in

A simple pendulum of time period T is suspended above a large horizontal metal sheet with uniformly distributed positive charge. If the bob is given some negative charge , its time period of oscillation will be

The time period of oscillation of a simple pendulum having length Land mass off the bob mis given as T. Ifthe length of the pendulum is increased to 4L and the mass of the bob is increased to 2m, then which one of the following is the new period of oscillation?

A simple pendulum has a string of length l and bob of mass m. When the bob is at its lowest position , it is given the minimum horizontal speed necessary for it to move in a circular path about the point point of suspension. The tension in the string at the lowest position if the bob is
