The distance between the plates of a parallel plate capacitor is 0.04m A field of 5000V/m is established between the plates and an unchanged metal plate of thickness 0.01m is inserted intothe condenser parallel to its plate. Find the p.d. between the plates (a) before the introducing of the metal plate and (b) after its introduction. what would be the p.d. if plate of dielectric constant K=2 is introduced in place of metal plate?
