A large spherical mass M is fixed at one position and two identical point masses m are kept on a line passing through the centre of M see figure The point masses are connected by a rigid massless rod of length 1 and this assembly is free to move along the line connecting them All three masses interact only through their mutual gravitational interaction When the point mass nearer to M is at a distance r 31 from M The value 288 M the tension in the rod is zero for m k of k is JEE Advanced 2015
