A parallel plate capacitor with plate area A and separation d has charge Q A slab of dielectric constant k is inserted in space between the plates almost completely fills the space IfE and C be the electric field and capacitance before inserting the slab then E A the electric field after inserting the slab is k B the capacitance after inserting the slab is k C C the induced charge on the slab is Q D the energy stored in the capacitor becomes U being the energy of the capacitor before
