A metal ball suspended from a long thread is held between the plates of a capacitor , as shown in Fig, How will the oscillations of this pendulum change, if the ball and the plates of two capacitor are charged ?

A small metal ball of mass m is suspended from a thread of length l between the plates of a large plane capacitor. How will the period of oscillations of such a pendulum change, if a charge + q is placed on the ball and the upper plate is positively charged

A small metal ball of mass m is suspended from a thread of length l between the plates of a large plane capacitor. How will the period of oscillations of such a pendulum change, if a charge + q is placed on the ball and the upper plate is negatively charged?

Displacement current is present between the plates of capacitor when the charge on the capacitor is

Displacement current exists between the plates of capacitor , when charge of the capacitor

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

A small conducting sphere is hanged by an insulating thread between the plates of a parallel plate capacitor as shown in figure. The net force on the sphere is

How capacitance changes if the distance between the plates of a parallel plate capacitor is halved?

Separation between the plates of a capacitor is increased from d to 2d while the battery remains connected with the plates. How will the stored energy in the capacitor change?
