A parallel plate capacitor has a uniform electric field ' $\displaystyle \overrightarrow{\mathrm{E}}$ ' 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 : ( $\displaystyle \varepsilon_0=$ permittivity of free space)
Official answer
From NTA’s final answer key for this paper.
(3)
$\displaystyle \frac{1}{2} \varepsilon_0 \mathrm{E}^2 \mathrm{Ad}$
