A tunnel is dug across the diameter of earth. A ball is released from the surface of Earth into the tunnel. The velocity of ball when it is at a distance (R )/(2) from centre of earth is (where R = radius of Earth and M = mass of Earth)

Assume that a tunnel is dug across the earth (radius=R) passing through its centre. Find the time a particle takes to reach centre of earth if it is projected into the tunnel from surface of earth with speed needed for it to escape the gravitational field to earth.

A tunnel is dug in the earth across one of its diameter. Two masses m and 2m are dropped from the two ends of the tunel. The masses collide and stick each other. They perform SHM , the ampulitude of which is (R = radius of earth)
