92. Two small spheres of masses M, andMy are suspended by weightless insulatingthreads of lengths L and L2. The spherescarry charges Q, and Q2 respectively. Thespheres are suspended such that they arein level with one another and the threadsare inclined to the vertical at angles of82 and 82 as shown. Which one of thefollowing conditions is essential, if0=62(a) M, M, but Qi = Q2(b) M = M2(c) Q = Q2(d) L1 = L293. Two identical conducting balls A andB have positive charges qı and 42respectively. But qı = 42. The balls arebrought together so that they touch eachother and then kept in their originalpositions. The force between them is(a) Less than that before the balls touched(b) Greater then that before the balls touched(c) Same as that before the balls touched(d) Zero |
