Electrostatic Potential and Capacitance

A parallel plate capacitor has a uniform electric field E⃗\vec E in the space between the plates. If the distance between the plates is dd and the area of each plate is AA, the energy stored in the capacitor is (ε0\varepsilon_0 = permittivity of free space):

  1. A.12ε0E2\dfrac12\varepsilon_0 E^2
  2. B.ε0EAd\varepsilon_0 EAd
  3. C.12ε0E2Ad\dfrac12\varepsilon_0 E^2 Ad✓
  4. D.E2Adε0\dfrac{E^2 Ad}{\varepsilon_0}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
