(1) Two small spheres with masses m 1 and m 2 hang on weightless insulating threads with l 1 and l 2 .The two spheres carry a charge of q 1 and q 2 respectively.The spheres hang such that they at are level with one another and the threads are inclined to the vertical at angles θ 1 and θ 2 .Which of the following condition is required for θ 1 and θ 1 to be equal? (a) m 1 =m 2 (b) q 1 =q 2 (c) l 1 =l 2 (d) none of these
