Solving a problem in physics section 75 point 5 electr

59. Two balls of the same radius and mass are suspended on threads of the same length so that their surfaces are in contact. After the charge balls were q0 = 0.4 μC, they pushed off from each other and separated by an angle of 2α = 60 °. Find the mass m of each ball if the distance from the center of the ball to the suspension point is l = 20 cm.
