E) none of these

Quizplus · Accepted Answer

The total charge on each capacitor must be equal since they are all in parallel. The formula for charge is Q = CV, where C is capacitance and V is voltage. Plugging in the values, we get Q = (500 x 10^-6 F) x 1000V = 0.5 C. Since each capacitor has two plates, the charge on each plate is 0.25 C. Therefore, the answer is B) 0.5.
