Solving a problem in physics section 74 point 46 electr

46. A thin silk thread withstands a tensile force of 9.8 ∙ 10−3 N. A 0.67 g ball suspended on this thread has a charge q1 = 1.1 ∙ 10−9 C. From below, in the direction of the suspension line at a distance of 1.8 cm, a ball having a charge q2 of the opposite sign is brought to it. At what charge q2 can the thread break? Express the answer in (nC).
