A parallel plate air capacitor of capacitance C is connected to a cell of emf V and then disconnected from it. A dielectric slab of dielectric constant K, which can just fill the air gap of the capacitor, is now inserted in it. Which of the following is incorrect? (a) The energy stored in the capacitor decreases K times. (b) The chance in energy stored is CV (1-1) K (c) The charge on the capacitor is not conserved. (d) The potential difference between the plates decreases K times. A parallel plate air capacitor of capacitance C is connected to a cell of emf V and then disconnected from it.
