Quizplus · Accepted Answer

When the plates of a parallel-plate capacitor are pulled apart while maintaining a constant voltage, the capacitance decreases. Since capacitance (C) is related to charge (Q) and voltage (V) by the equation Q = C * V, and V is constant, a decrease in capacitance results in a decrease in charge.
