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

A planet of mass M, has two natural satellites with masses m 1 and m 2 . The radii of their circular orbits are R 1 and R 2 respectively. Ignore the gravitational force between the satellites. Define v 1 ,L 1 ,K 1 and T 1 to be respectively, the orbital speed, angular momentum, kinetic energy and time period of revolution of satellite 1; and v 2 ,L 2 ,K 2 and T 2 to be the corresponding quantities of satellite 2. Given m 1 /m 2 = 2 and R 1 /R 2 = 1/4, match the ratios in List – I to the numbers in List -II.
