A parallel plate capacitor is charged. If the plates are pulled apart

A air filled parallel plate capacitor having circular plates of diameter D is given a charge Q.The magnitude of the force acting between plates is

A parallel plate vacuum capacitor eith plate area A and separation x has charges +Q and -Q on its plates. The capacitor is disconnected from the source of charge, so the charge on each plate remains fixed. a. What is the total energy stored in the capacitor? b. The plates are pulled apart an additional distance each case. c. If F is the force with which the plates attract each other, the change in the stored energy must equal the work dW =F dx done in pulling the plates apart. Find an expression for F d. Energy storage in a capacitor can be limited by the maximum electric field between the plates. What is the ratio of the electric field for the series for parallel combinations?

A parallel plate vacuum capacitor with plate area A and separation x has charges +Q and -Q on its plates. The capacitor is disconnected from the source of charge, so the charge on each plate remains fixed. (a) What is the total energy stored in the capacitor? (b) The plates are pulled apart an additional distance dx. What is the change in the stored energy? (c) If F is the force with which the plates attract each other, then the change in the stored energy must equal the work dW = Fdx done in pulling the plates apart. Find an expression for F . (d) Explain why F is not equal to QE , where E is the electric field between the plates.
