The Coulomb force between two charges in a medium is given by Coulomb’s law, which states that the force is inversely proportional to the dielectric constant (relative permittivity) of the medium. Water has a high dielectric constant, which significantly reduces the Coulomb force between the charges.
The dielectric constant of water is approximately 78. Therefore, the Coulomb force between two charges placed in water is reduced to:
C. 1/78 times
