Two charge when kept at a distance of `1m` apart vacuum have a some force of repulsion .if the force of repulsion between these two charges be same ,whenplaced in an oil of dielectric constant `4`the distance of separation is

There is force of repulsion between two like charges, because electric lines of force

What is the force of repulsion between two charges of 1C each, kept 1m apart in vacumm ?

The force of interaction between two charges placed in vacuum is F . What will be the force be the force between the charges placed at the same distance in a medium of dielectric constant K ?

Explain attraction and repulsion between two charges on the basis of electrostatic lines of force.

Two point charges separated by a distance d apart each other with a repulsion force 9.N. if the separation between becomes 3d, the force of repulsion will be -

The force of repulsion between two identical positive charge when kept with a separation r in air is F. Half the gap between the two charges is filled by a dielectric slab of dielectric constant = 4 Then the new force of repulsion between those two charges become
