45 In gravity free space a thin spherical shell of mass M and radius Ris held fixed There is a small hole in the shell A small mass m is released from rest at a distance R 4 from the hole along a line that passes through the hole and also through the centre of the bshell The time taken by the particle to travel from the hole to the point diametrically opposite is a 2r R GM 10R3 b m me R 4 M c 2R3 d 3R3
