The point masses are connected by rigid massless rod of length l and this assembly is free to move along the line connecting them. All three masses interact only throght their mutual gravitational interaction. When the point mass nearer to M is at a distance r = 3 l form M, the tension in the rod is zero for m = k( M/288 ). The value of k is

A spherical body of radius R consists of a fluid of constant density and is in equilibrium under its own gravity. If P ( r ) is the pressure at r ( r < R) then the correct option(s) is (are)
