Question

22. The force between two charges placed in vacuum is F. what happens to the force if the two charges are
dipped in kerosene oil of di-electric constant K=2.​

Answer 1

Explanation:

Force is inversely proportional to Relative Permittivity.

Therefore Greater the Dielectric Constant, lesser the force.

Hence Force'= F/2 as K=2

Answer 2

The force between the two charges remain same but if we change the dielectric what will be change in force.

• The force and the dielectric constant are inversely proportional to each other.
• Which mean if the dielectric value increases the force will going to be less or vice versa.
• As in the question K=2 which means the force will be less.
• The effective dielectric increases, the force between the charged particles will be less.
