Two small spheres with masses m1 and m2 hang on weightless, insulating threads of lenght L1 and L2. The two spheres carry charges q1 and q2. The spheres hang such that they are at the same level with one another the threads are inclined at angle r1 and r2 with vertical. Show that the angle r1 and r2 will be equal when m1=m2, L1=L2.
