7 Suppose a smooth tunnel is dug along a straight line joining two points on the surface of the earth and a particle is dropped from rest at its one end Assume that mass of earth is uniformly distributed over its volume Then a the particle will emerge from the other end with velocity GM V 2R respectively 9 where M and R are earth s mass and radius e b the overlapping will come to rest at centre of the tunnel c potential energy of the particle will be equal to zero at centre of tunnel if it is along a diameter d acceleration of the particle will be proportional to its distance from mid point of the tunnel ing in a circular orbit round the certain noin
