Two circular electrodes with a diameter of 5.0 mm and a 0.10 mm-thick sheet of Mylar between them are attached to a 9.0 V battery. The battery is disconnected and then the Mylar is withdrawn. (Very small spacers keep the electrode separation unchanged.)

κ = 3.1 for Mylar.

A)What is the charge on the electrodes after the Mylar is withdrawn?

b)What is the potential difference across the electrodes after the Mylar is withdrawn?

c)What is the electric field between the electrodes after the Mylar is withdrawn?

Thank you so much!!!!
