Solving a problem in physics section 75 point 60 electr

60. Two balls of the same radius and mass are suspended on threads of the same length so that their surfaces are in contact. What charge q needs to be reported to the balls so that the tension force of the threads becomes T = 98 mN? The distance from the center of the ball to the suspension point l = 10 cm; the mass of each ball is m = 5 g.
