(1)A charge of 50C produces an electric field intensity of 2x10^3V/m at a distance of 3cm. Calculate the value of another charge placed at the same distance in the same medium which gives rise to an electric field intensity of 1.5x10^3V/m.
(2) A charge of 30C has an electric field intensity of 3x10^3V/m at a distance of 4cm. Calculate the value of the electric field intensity when the distance is doubled. Please show working thanks.?
