An initially uncharged parallel plate capacitor is connected to a circuit containing a battery with emf -35V and a resistor, R = 3.3M2 as shown in the figure to below. The capacitor whose plates have an area of A= 5.2mm² are separated by a distance of d=3.2mm and one third of the capacitor is filled with a dielectric material, *₁ = 2.5 and the rest (two thirds) is filled with another dielectric material, K₂ = 6.3. At t=0 the switch is closed. 3.6 seconds after the switch is closed the electric field within the first dielectric material (₁) is observed to be 9 x 10³ N/C. Find the potential difference across the capacitor at this instant (t = 3.6s) in terms of permitivity of free space ? Express your answer using zero decimal place. R
