(a) A parallel plate capacitor is filled by a dielectric whose relative permittivity varies with the applied voltage (U) as ε = αU where α = 2V-1. A similar capacitor with no dielectric is charged U0= 78 V. It is then connected to the unchanged capacitor with the dielectric. Find the final voltage on the capacitors.\n(b) A capacitor has some dielectric between its plates, and the capacitor is connected to a DC source. The battery is now disconnected, and then the dielectric is removed. State whether the capacitance, the energy stored in it, the electric field, the charge stored, and the voltage will increase, decrease or remain constant. π² PW App Link - https://bit.ly/YTAI_PWAP π PW Website - https://www.pw.live/
