A 0.120 pF parallel-plate capacitor is charged to a potential difference of 10.0 V and then disconnected from the battery. A cosmic ray burst creates 1.00 × 10^6 electrons and 1.00 × 10^6 positive charges between the plates. If the charges do not recombine, but reach the oppositely charged plates, by how much is the potential difference between the capacitor plates reduced?

a. 1.33 V b. 7.34 V c. 8.67 V d. 1,330 V e. 8,670 V
