A tunnel is dug across the earth along a chord AB as shown A particle is projected inside the tunnel from end A with an initial velocity vo 3g R 2 there is no friction between the tunnel and the particle Then choose the correct option s where go gravitational acceleration on the surface of Earth R radius of earth B Vo Ve 30 R 3g R 2 A A The time taken by the particle to move from end A to other end B of the tunnel is R 3 19 B The time taken by the particle to move from end A to other end B of the tunnel is 2 R 3 9 C The maximum speed of the particle inside the tunnel is gR D The maximum speed of the particle inside the tunnel is 2g R
