Two parallel plates, each having area A = 2797 cm2 areconnected to the terminals of a battery of voltage Vb = 6 V asshown. The plates are separated by a distance d = 0.51 cm.
1)What is Q, the charge on the topplate? _____C
2)
What is U, the energy stored in the thiscapacitor?
_____J
3)
The battery is now disconnected from the platesand the separation of the plates is doubled ( = 1.02 cm). What isthe energy stored in this new capacitor?
_____J
4)
What is E, the magnitude of the electric field in theregion between the plates?
