A small electrically charged ball is positioned at a certain distance in front of a metal plate lying at earth potential. The surface charge on the plate due to electrostatic induction together with the charged ball forms an electric field analogous to that which exists between two oppositely charged point charges. The electrostatic force acting on the ball can be measured with a sensitive torsion dynamometer.
Set the desired force on the dynamometer for a given distance between ball and plate, charge the ball and wait until the charge has dropped far enough for the dynamometer to return to the starting position, then immediately measure the charge. Repeat this procedure for different distances between conductor ball and conductor plate. Limit the distances to the range between 4 cm and 8 cm since, when the distances are smaller, the charge on the conductor ball is largely transferred to the plate through electrostatic induction and, when the distances are larger, the electric field is disturbed by the surroundings and the edges of the condenser plate.
