An infinite thin plate sheet of charge density 10-⁸C/m² is held in air . What is the potential difference between two equipotential surfaces separated by distance 8.85 X 10^-3 m near it?

Charge  density = 10^-8 C/m^2
Distance = 8.85 X 10 -3 m
Potential difference = Charge density* distance
                                     = 10^-8 *8.85 X 10^-3
                                     = 8.85 *10^-11 C/m
