Statement I : Force between two charges decreases when air separating the charges is replaced by water.
Statement II : Medium intervening the charges has no effect on force.

Statement-1. Force between two charges increases, when air separating the charges is replaced by water. Statement-2. Medium intervenning between the charges has dielectric constant K gt 1 .

Force between two charges separated by a distance r varies as r^(2) ?

How the force acting between two charges will change if the air medium betweeen them is replaced by metalic plate?

When a brass plate is introduced between two charges, the force between the charges

If the air medium between the two charges is replaced by water what change you expect in the electrostatic force and why?
