A50.0 nf air-filled parallel plate capacitor is connected in series with a 2.85 kn resistor and a battery of emf 36.0 v. (a) determine the final charge on the capacitor. (b) once the capacitor is fully charged and there is no current in the circuit, a sheet of plastic with a dielectric constant of 2.75 is introduced in the gap between the plates of the capacitor, completely filling the gap. if the area of each plate is 0.275 m² what is the electric field inside the plastic immediately after it is inserted (before there is any change in the charge on the plates of the capacitor)? n/c
