The capacitance of a capacitor depends on:

Two identical charged spherical drops, each of capacitance $C$, merge to form a single drop. The resultant capacitance is

Which one of the following is the correct dimensional formula for the capacitance in $F$? $M, L, T$ and $C$ stand for units of mass,length,time,and charge respectively.

The capacity of a conductor does not depend upon:

The ratio of charge to potential of a body is known as

$A$ capacitor of unknown capacitance $C$ is connected across a battery of $V$ volt. The charge stored in it becomes $Q$ coulomb. When the potential across the capacitor is reduced by $V^{\prime}$ volt,the charge stored in it becomes $Q^{\prime}$ coulomb. The capacitance $C$ is:
