A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them. When it is connected to a battery of voltage V0, it has charge of magnitude Q0 on its plates. It is then disconnected from the battery and the plates are pulled apart to a separation 2d without discharging them. After the plates are 2d apart, the magnitude of the charge on the plates and the potential difference between them are what?
   
  a.
  Q0, V0
   
  b.
  Q0, V0
   
  c.
  Q0, V0
   
  d.
  Q0, 2V0
   
  e.
  2Q0, 2V0

Question 2

  b.
  13 mJ
   
  c.
  28 mJ
   
  d.
