Calculate the displacement current between square plates in which electric field changes at the rate of \(5 \times 10^{12} {Vm}^{-1} {~s}^{-1}\). Side of plates is \(2.0 {~cm}\).

The mean distance of mars from the sun is 1.5 times that of earth from the sun. What is approximately the number of years required by mars to make one revolution about the sun?

The relation between radius of curved road and banking angle is:

Which among the following is the incorrect statement regarding displacement current?

Find the electric charge \({Q}_{1}\) on plates of capacitor \({C}_{1}\), shown in Figure 3 below:

The concept of displacement current was proposed by:

If a stone of mass m is rotated in a vertical circular path of radius \(1m\), the critical velocity will be: \(g=9.8 m/s ^{2}\)

There is a simple pendulum hanging from the ceiling of a lift. When the lift is standstill, the time period of the pendulum is \(T\). If the resultant acceleration becomes \(\frac{g }{ 4}\), then the new time period of the pendulum is:
