Show that in CGS system the magnitudes of the permitivity and the dielectric constant of a medium are numerically equal.

What do you mean by dielectric constant of a medium ? What is its unit ?

Prove that, in CGS system, the capacitance of a conducting sphere is numerically equal to its radius.

How does the force between two point charges change if the dielectric constant of the medium in which they are kept, increases?

Two charges of +40 esu and -35 esu separated by a distance of 10 cm, exert 4 dyn force on each other. Determine the dielectric constant of the medium.

A particle of mass 10 g moves along a circle of radius 6.4 cm with a constant tangential acceleration. What is the magnitude of this acceleration if the kinetic energy of the particle becomes equal to 8xx10^(-4) J by the end of the second revolution after the beginning of the motion ?

Write the value of electrostatic force constant in C.G.S. System.

The figure shows two identical parallel plate capacitor connected to a battery with the switch S closed. The switch is now opened and the free space between the plates of the capacitor is filled with a dielectric of dielectric constant 3. Find the ratio of the total electrostatic energy stored in both capacitors before and after the introduction of the dielectric.

The separation between the plates, each having an area of 1 m^2 , of a parallel plate capacitor is 0.01 cm. The medium in the intervening space has a dielectric constant of 7. The capacitor is charged to a potential of 300 V. Determine the energy stored in it.
