If $C$ is the capacitance and $V$ is the electric potential,then the dimensional formula of $C V^{2}$ is

$A$ parallel plate capacitor has a uniform electric field $E$ in the space between the plates. If the distance between the plates is $d$ and the area of each plate is $A$,the energy stored in the capacitor is:

$A$ parallel plate capacitor has a uniform electric field $\overrightarrow{E}$ in the space between the plates. If the distance between the plates is $d$ and the area of each plate is $A$,the energy stored in the capacitor is: ($\varepsilon_{0} =$ permittivity of free space)

When an uncharged capacitor is connected to a battery to charge it fully,

The energy required to charge a capacitor of $5\,\mu F$ by connecting a $d.c.$ source of $20\,kV$ is......$kJ$.

$A$ $700\,pF$ capacitor is charged by a $50\,V$ battery. The electrostatic energy stored by it is
