SOLVED
A plate of of Mass m contains an ice cube of mass M and side L. Find the shift in centre of mass when th ice melts.
(Gravity absent)
I think that the centre of mass will come down by ML/2(M+m)
But my book gives it zero. why?
What has gravity to do with centre of mass?? And yes, what's the difference between centre of gravity an centre of mass?
