An air-filled 4.8 nF parallel-plate capacitor is connected to a battery where it acquires a charge of 8.2 nC. A piece of plastic then is inserted between the plates of the capacitor while still connected to the battery and the charge on the capacitor now becomes 23 nC. What is the dielectric constant of the plastic K, and what is the emf of the battery &?
