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

Question 2

An initially uncharged parallel plate capacitor of capacitance C is charged to potential V by a battery. The battery is then disconnected. Which statement is correct?
 a. There is no charge on either plate of the capacitor.
  b. The capacitor can be discharged by grounding any one of its two plates.
  c. Charge is distributed evenly over both the inner and outer surfaces of the plates.
  d. The magnitude of the electric field outside the space between the plates is approximately zero.
  e. The capacitance increases when the distance between the plates increases.

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
