1kya hero log ,darr gaye atlest nis bhaiya!!
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/√(GMh)
b)>R2/√(GMh)
c)<R2/√(GMh)
d)none

1kya bhaiya ,no one touching it , arrre subjective questoin se mat daro pals!!!
1I 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.
