Shown in the figure below is a device used to detect charge placed on a small ball. The violet ball, has known charge Q = 5e-08 Coulombs and is fixed in place. The blue ball (m = 0.00106 kg) is suspended by a string of length L = 0.124 meters. At the moment shown in the figure, the blue ball hangs at an angle ? = 14.2 degrees off the vertical.
