Решение задачи по физике раздел 75 пункт 62 электро

62. Two small charged balls in vacuum of mass m = 27 mg each are suspended at one point on light silk threads of the same length l = 20 cm. The balls are separated so that the angle between the threads is α = 90 °. If the charge of the first ball q1 = 40 nC, then the charge of the second ball q2 is ... nC.
