Answer:

Relative permittivity (also called dielectric constant) of a medium is the ratio of the absolute permittivity of the medium to that of the permittivity of free space. ... Relative permittivity of water is 81 means: an electric field that has strength E in vacuum will have strength E/81 inside water.
