Answer the following: How i)much work is done in moving a 500uC charge between two points on an equipotential surface? ii)does the force between two charges change, if the dielectric constant of the medium in which they are kept increases?

On equipotential surface there is no work done to move charge from place to another.
If the dielectric constant of medium increases , the force will decrease because force is inversly proportional to dielectric constant
