In the above problem, if the battery is disconnected before inserting the dielectric, then difference will be

Solve the above problem when a thin metal sheet is inserted, separating dielectric 1 and 2 from 3 .

The resonant frequency of L-C circuit is f_0 before insertion of dielectric of (dielectric constant) (E_r = 4) . After inserting the dielectric, the resonant frequency will be

A parallel plate capacitor is charged by a battery. After some time the battery is disconnected and a dielectric slab of dielectric constant K is inserted between the plates. How would (i) the capacitance, (ii) the electric field between the plates and (iii) the energy stored in the capacitor, be affected ? Justify your answer.
