    Answer:

    C

    Explanation:

    From the formula

    Q = CV

    Where the V = voltage across a parallel plate capacitor

    Q = charge

    If V is doubled, automatically charge Q will also be doubled.

    From the energy formula.

    E = 1/2 CV^2

    If voltage V is doubled, energy E will be squadripple.

    Electric field strength E = V/d

    If V is doubled E is also double.

    Therefore, Doubling the voltage across a parallel plate capacitor does not double which of the following?

    WhIch is the energy stored
