there are two concentric bodies of same mass one sphere of radius R and other concentric shell with radii R . the outer shell has a tiny hole in it so that samll particle can penetrate it .

A small particle of mass m is released from 2R+h from their common centre(h<<R) such that finds its way through the hole .find the time taken by the particle to more from the hole to the inner sphere

a)=R²/âˆš(GMh)
b)>R²/âˆš(GMh)
c)<R²/âˆš(GMh)
d)none

I think there's a typing error. You've given the radius of both the sphere and the shell to be R. I think the radius of the shell should be 2R.
