What will be elongation in an ideal spring of
if it is hung vertically with no mass at the bottom?
Assume the spring obeys Hooke's Law and is sensitive enough to elongate a bit due to gravity.
I think it would be assuming it wouldn't make a difference if I take all mass at the bottom.
What do you think?

See my answer to this question.
I hope it is 2mg/k,by considering the elongation of centre of mass...right na?

Yeah it seems plausible but can't be sure as mg/k is as much appealing.
Yes, as mg=- kx

Why it can't be 2mg/k as suggested by Vinayakraj M above?

Yes it should be 2mg/k because the position of COM is twice the original position if u take all the mass at the bottom...he's ri8..
Yeah
