then the correct option(s) is (are)
A larger 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. 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

Gravitational acceleration on the surface of plane for root 6 /11 g. where g is the gravitational acceleration on the surface of the earth. The average mass density of the planet is 23 times that of the earth. If the escape speed on the surface of the earth is taken to be 11 km/s the escape speed on the surface of the planet in km/s will be
