An initially uncharged parallel plate capacitor is connected to a circult containing a battery with emf 20V and a resistor, R 8.8M as shown in the figure to below. The capacitor whose plates have an area of A = 5.9mm² are separated by a distance of d = 4.6mm and one third of the capacitor is filled with a dielectric material, ₁3 and the rest (two thirds) is filled with another dielectric material, ₂-2.1. At t=0 the switch is closed. 7.8 seconds after the switch is closed the electric field within the first dielectric material (x) is observed to be 12 x 10 N/C.
