Parallel Plate Capacitors with and without Dielectric

A parallel plate capacitor with oil as a dielectric between the plates has a capacitance C. if the oil, with dielectric constannt (K=3), is removed, then the capacitance of the capacitor will be

An unchanged capacitor with a solid dielectric is connected to a similar air capacitor charged to a potential of V_(0). . If the common potential after sharing of charges becomes V, then the dielectric constant of the dielectric must be

parallel plate capacitor is filled by a dielectric whose dielectric constant varies with the applies voltage (V) as K = 2V. A similar capacitor with no dielectric is charged to V_(0)=78 volt.It is then connected to the uncharged capacitor with the dielectric.Find the final voltage on the capacitors

A parallel palte capacitor is filled by a dielectric whose relative permittively varies with the applied voltage (U) as epsilon = alpha U where alpha = 2V^(-1) . A similar capacitor with no dielectric is charged to U_(0) = 78V . It is then is connected to the uncharged capacitor with the dielectric. Find the final voltage on the capacitors.

A parallel plate capacitor with a dielectric slab with dielectric constant k= 3 filling the space between the plates is charged to potential V and isolated. Then the dielectric slab is drawn out and another dielectric slab of equal thickness but dielectric constant k'= 2 is introduced between the plates. The ratio of the energy stored in the capacitor later to that initially is:
