Question

The plate of a parallel plate capacitor are 7mm apart and 1m²in area the plate are in vacuum if the pd applied is 100 volts across it's capacitor calculate the capacitance, charge on each plates and electric intensity

Answer 1

The capacitance:

$$C=\dfrac{\epsilon_0 A}{d}=2.29·10^{-17}\text{ F}.$$

The charge is

$$Q=CV=2.29·10^{-15}\text{ C}.$$
