Now this space is filled by a slab of dielectric constant K. The capacitor is connected to a battery emf V and the slab is taken out. (A) Charge (K1)C0V flow through the battery (B) Energy (K−1)C0V^2 is absorbed by the cell (c) The external agent has to do 1/2(K−1)C0V^2 amount of work to take the slab out (D) the heat produced in connecting wires is 1/2(K−1)C0V^2
