A parallel plate capacitor has a uniform electric field ' \(\vec{E}\) ' in the space between the plates. If the distance between the plates is ' \(d^{\prime}\) and the area of each plate is ' \(A\) ', the energy stored in the capacitor is: \(\left(\varepsilon_{0}=\right.\) permittivity of free space)
A \(\frac{1}{2} \varepsilon_{0} E^{2}\)
B \(\varepsilon_{0} E A d\)
(c) \(\frac{1}{2} \varepsilon_{0} E^{2} A d\)
D \(\frac{E^{2} A d}{\varepsilon_{0}}\)
