Problem
At a point 0.30 m away from an isolated point charge in air, the magnitude of the electric field is measured to be 360 N C−1.
(i) Calculate the magnitude of the electric field at a point 0.60 m from the charge along the same radial line.
(ii) Determine the distance from the charge at which the field magnitude will be 40 N C−1. Show all steps clearly.
