An initially uncharged parallel plate capacitor is connected to a circuit containing a battery with emf &-39V and a resistor, R=2.4M as shown in the figure to below. The capacitor whose plates have an area of A = 2.9mm² are separated by a distance of d = 6.1mm and one third of the capacitor is filled with a dielectric material, K₁ = 3.4 and the rest (two thirds) is filled with another dielectric material, K₂=4.5. At t=0 the switch is closed. 5.4 seconds after the switch is closed the electric field within the first dielectric material (₁) is observed to be 19 x 10³ N/C. Find the potential difference across the capacitor at this instant (t = 5.4s) in terms of permitivity of free space q? Express your answer using zero decimal place. R Answer:
