An isoscles right angle tunel ABO is made inside the earth from suraceof earth to its centre as shown in the fgure The distance between the points A and B and that between the points B and O is R 2 where R is the radius of earth The surface of tunnel is assumed to be frictioniess A smallparticle of mass m s released from point A The collisin between the particde and the tunnel is assumed to be perfetly elastic Take mas of earth M radius of earth R 6400 km and g 10 m s then find i The time taken by the particle to move in the tunnel from A to O and also find ii work done by gravitation field of earth on the particle to reach from B to 0 A B
