3 A Vo kloge 5 D V klog GM 28 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 1 A The particle will emerge from the other end with velocity radius respectively B The particle will come to rest at centre of the tunnel because at this position particle is closest to Earth centre C Potential energy of the particle will be equal to zero at centre of tunnel if it is along tunnel s diameter D Acceleration of the particle will be proportional to its distance from midpoint of the tunnel particle of mass m is transferred from the centr where M and R are Earth s mass and
