A 016 PF Parallel-Plate Capacitor Is Charged to 10 V

A 0.16 pF parallel-plate capacitor is charged to 10 V. Then the battery is disconnected from the capacitor. When 1.00 × 107 positive charges of magnitude |e| are now placed on the positive plate of the capacitor, the voltage between the plates changes by

A) −5.0 V.
B) −1.1 V.
C) 0 V.
D) +1.1 V.
E) +5.0 V.
