An initially uncharged parallel plate capacitor is connected to a circuit containing a battery with emf -15V and a resistor, R = 8.5MN as shown in the figure to below. The capacitor whose plates have an area of A = 3.1mm² are separated by a distance of d = 3.4mm and one third of the capacitor is filled with a dielectric material, K₁= 1.1 and the rest (two thirds) is filled with another dielectric material, K₂=4.5. At t=0 the switch is closed. 7.1 seconds after the switch is closed the electric field within the first dielectric material (₁) is observed to be 15 x 10³ N/C.
