Problem
The plates of a parallel-plate capacitor are separated by a solid dielectric. This capacitor and a resistor are connected in series across the terminals of a battery. Now the plates of the capacitor are pulled slightly farther apart. When equilibrium is restored in the circuit,
(a) the potential difference across the plates has increased.
(b) the energy stored on the capacitor has increased.
(c) the capacitance of the capacitor has increased.
(d) the charge on the plates of the capacitor has decreased.
