2) A parallel plate capacitor of plate area A=6x10-2 m2 is partially filled with a dielectric material with permittivity ε=3ɛo and thickness d2=10-3m as shown in the figure. While a battery of Vo=10 Volts is connected to the capacitor, the upper plate of the capacitor is allowed to move under the electric field forces so that di changes from 3x10-3m to 2x10-3m. a) Calculate the change in the charge on the upper plate. Is it increased or decreased? b) Calculate the change in the stored electrostatic energy. Does it increase or decrease? c) Find the extra energy supplied by the battery during the motion. d) Find the mechanical work done by the electric force to move the plate A EO di E d2
