Q. One of the plates of capacitors is connected to a source of constant negative potential and the electrons accumulated on it are $10^{12}$. When the other plate is earthed, the number of electrons now present on the plate will be :

Electrostatic Potential and Capacitance

Solution:

When the other plate is earthed, the potential of the first plate falls. So, additional charge or electrons will come to the plate from the source of emf.
