A parallel plate capacitor with plates of area (A) and plate separation (d) is charged so that the potential difference between its plates is (V). If the capacitor is now disconnected from the power source and its plate separation is increased to 2d, which statement is correct? a) The voltage between the plates is unchanged.
b) The voltage between the plates is decreased to one-half its original value.
c) The charge on the plates is decreased to one-half its original value.
d) The capacitance is unchanged.
e) The capacitance is increased two times its original value.
f) The charge on the plates is increased two times its original value.
g) The capacitance is decreased to one-half its original value.
