Explanation:
If the space between the charges is completely filled with dielectric of constant 4 the force becomes F2 .
If two charges are kept in a medium, then the force between them decreases by factor of relative permittivity of medium.
Relative permittivity of water is 80. So, the force between the two charges will decrease by 80 times.
Hence, new force will be f/80.
