A parallel plate capacitor of capacitance Co has plates of area A with separation d between them. When it is connected to a battery of voltage Vo, it has charge of magnitude Qo 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, by what factor does the capacitance change? By what factor does the potential difference between the plates change?

An air-filled parallel-plate capacitor has plate area A and plate separation d. The capacitor is connected to a battery that creates a constant voltage V.A) Find the energy U_0 stored in the capacitor. Express your answer in terms of A, d, V, and ϵ_0.B) The capacitor is now disconnected from the battery, and the plates of the capacitor are then slowly pulled apart until the separation reaches 3d. Find the new energy U_1 of the capacitor after this process. Express...

A parallel plate capacitor has a charge Q, plates of area A and separation d, where , so that we can disregard the fringe field. Show that the magnitude of the force exerted on each plate by the other is F = Q2/(2e0A).You may use (with care!) the expression F = QE, or consider the change in potential energy of the capacitor as you change the separation of the plates. Or you may do both.
