A 0120-PF Parallel-Plate Capacitor Is Charged to a Potential Difference of of 10.0

question 44

Multiple Choice

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 × 106 electrons and 1.00 × 106 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
