In an electricity experiment, a plastic ball of mass m is attached to a string of length L and given an electric charge. The string is tied to a charged plane, inclined at an angle o to the horizontal. The electric field exerts an unknown force FE perpendicular to the plane causing the ball to swing up until the string is horizontal and remains still. What is the magnitude of the tension in the rope? /electric force In an electricity experiment, a plastic ball of mass m is attached to a string of length L and given an electric charge.
