A small plastic ball of mass m = 1.50 g is suspended by a string of length L = 17.0 cm in a uniform electric field, as shown in the figure below. If the ball is in equilibrium when the string makes a ? = 17.0° angle with the vertical as indicated, what is the net charge on the ball? A ball of mass m is attached to a string of length L and suspended from the ceiling. The string makes an acute angle ? with the normal line from the ceiling, such that the string and ball are displaced to the right of the normal line. To the right of the string and ball, five parallel, evenly-spaced, identical arrows point to the right. The arrows are vertically stacked and labeled with E = 1.00 ✕ 103 N/C. To the left of the string and ball, x y-coordinate axes demonstrate that the +x-axis points to the right and the +y-axis points up.
