A tiny ball of mass 0.6g is suspended from a rigid support with a piece of thread in a horizontal electric field of intensity 700N/C. The ball is in equilibrium when the thread is inclined at an angle of 20degrees to the vertical.WHat are the magnitude and the sign of the charge on the ball? take g = 9.8m/s^2
