Problem
Two point charges +5.0μC at the origin and −5.0μC on the x-axis at x=0.30m are immersed in pure water of relative permittivity 80.
(a) Calculate the magnitude of the force on the charge at the origin.
(b) State the direction of this force.
(c) If the same arrangement were in air, by what factor would the magnitude of the force change?
