An air capacitor is given a charge of `2muC` raising its potential to 200 V. If on inserting a dielectric constant its potential falls to 50V, what is the dielectric constant of the medium?

In a parallel plate capacitor, the capacitance increases from 4 muF to 80muF no introduicng a dielectric medium between the plates. What is the dielectric constant of the medium?

An air capacitor of capacitance 2muF is charged to a potential 200 V. What is the energy stored in it? If a medium of dielectric constant 2 is inserted between its plates and the potentials is raised again to the same value, what is the amount of energy, it would store?

The electric potential at a point in the electric field is V. What is the electric potential energy of a charge q_0 placed at that point?

A parallel plate capacitor has a capacity of 6 muF (Micro farad), with air in between the plates and 60 muF (Micro farad) when dielectric medium is introduced.What is the dielectric Constant (K ) of the medium ?

Define dielectric constant of a medium in terms of fore between two electic charges.

Dielectric constant of a medium is unity. What will be its perimitivity?

A capacitor carring a charge equal to 2muC up to a potential 100 V is put into contact with another capacitor carrying a charge of 1.5mu C up to a potential of 60 V. What is the resulting potential, the charge carried by each, the total energy before and after connection?
