Two parallel plates, each having area A= 3115 cm2 are connected to the terminals of a battery of voltage Vb = IE: V as shown. The plates are separated by a distance d = 0.41 cm. 1) What is Q. the Charge on the top plate? C Submit + 2) What is U, the energy stored in the this capacitor? J Submit 4. 3) The battery is now disconnected from the plates and the separation of the plates is doubled I: = 0.82 cm). What is the energy stored in this new capacitor? J- 4) What is E. the magnitude of the electric fieLd in the region between the plates? wc
