PhysicsElectrostatic Potential and CapacitanceNEET 2006

A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates:-

Answer: (4)

Solution

After the battery is disconnected the charge on the plates stays constant. Capacitance decreases when the separation is increased. Since , with constant and decreasing, the
