An initially uncharged air-filled capacitor is connected to a 3.013.01 V charging source. As a result, 9.91×10−59.91×10−5 C of charge is transferred from one of the capacitor's plates to the other. Then, while the capacitor remains connected to the charging source, a sheet of dielectric material is inserted between its plates, completely filling the space. The dielectric constant ????κ of this substance is 7.917.91 . Find the voltage ????V across the capacitor and the charge ????fQf stored by it after the dielectric is inserted and the circuit has returned to a steady state.
