A parallel-plate capacitor has capacitance CC =12.5 pFpF when the volume between the plates is filledwith air. The plates are circular, with radius 3.00 cmcm. Thecapacitor is connected to a battery and a charge of magnitude25.0 pCpC goes onto each plate. With the capacitor stillconnected to the battery, a slab of dielectric is inserted betweenthe plates, completely filling the space between the plates. Afterthe dielectric has been inserted the charge on each plate hasmagnitude 45.0 pCpC.
1. What is the dielectric constant KK of thedielectric?
2. What is the potential difference between the platesbefore the dielectric has been inserted?
3. What is the potential difference between the platesafter the dielectric has been inserted?
4. What is the electric field at a point midway between theplates before the dielectric has been inserted?
5. What is the electric field at a point midway between theplates after the dielectric has been inserted?
