Two planets A and B are fixed at a distance d from each other as shown in the figure.If the mass of A is `M_A` and that of B is `M_B`, then find out the minimum velocity of a satellite of mass Ms projected from the mid point of two planets to infinity .

Two planets A and B are at distances of 10^(9) m and 10^(11) m from the sun respectively. Calculate the ration of speeds of the two planets.

A chain of mass 'm' is attached at two points A and B of two fixed walls as shown in the figure. The tension in the chain at A is

Two blocks A and B each of equal masses m are rleased from the top of a smooth fixed wedge as shown in the figure. Find the magnitude of the accelertion of the centre of mass of the two blocks.

The radius of the planet A is half the radius of planet B. If the mass of A is M_(A) What must be the mass of B so that the alueof g on B is half that of its value on A?

The escape velocity of a satellite from the surface of a planet is sqrt(2) times the orbital velocity of the satellite. If the ratio of the masses of two given planets is 1 : 4 and that of their radii is 1 : 2, respectively, then find the ratio of escape velocities of a satellite from the surfaces of two planets.
