If the plate separation of the capacitor in Exercise 39 changed to 10.48 mm after the capacitor is disconnected from the battery, how do your answers change?
A12.0-V battery remains connected to a parallel plate capacitor with a plate area of 0.224 m2 and a plate separation of 5.24 mm.
(a) What is the charge on the capacitor?
(b) How much energy is stored in the capacitor?
(c) What is the electric field between its plates?
