An isosceles right angle tunnel ABO is made inside the earth from surface of earth to its centre as shown in the higure The R distance between the points A and B and that between the points B and O is where R is the radius of earth The surface 2 tunnel is assumed to be frictionless A small particle of mass mo is released from point A The collision between the particle 6400 km and and the tunnel is assumed to be perfectly inelastic Take mass of earth is M Radius of earth R g 10 m s Now answer the following question A Or R B 2 The time taken by the particle to move in the tunnel from A to O 1600 S 800T S 400 S
