A parallel plate capacitor is charged. If the plates are pulled apart

A parallel plate capacitor is charged by connecting is plates to the terminals of a battery. The battery remains connected to the condenser plates and a glass plate is interposed between the plates of the capacitor, then

A parallel plate capacitor is connected to a battery. The plates are pulled apart with uniform speed. If x is the separation between the plates, then the rate of change of electrostatic energy of the capacitor is proportional to

A parallel plate capacitor is charged and then disconnected from the battery. If the plates of the capacitor are moved farther apart

A parallel plate capacitor is charged and then isolated. On increasing the plate separation
