yeah this statement is true but not always
look i will give u an example
spose u have a board whose centre of mass ofcourse is at its geometrical centre
now cut two pieces of the board from opposite side but of same size and paste them in each other's place
the position of particles has ofcourse changed but the com now also will lie at its initial position.Wat say?
If u still have some doubt, consider a solid sphere
if u sumhow scoop a concentric sphere out of the original sphere, and paste the scooped material evenly on the surface of the hollow shell that u wud obtain after scooping, the position of com wont change
but if u dont paste it evenly, the position of centre of mass wud ofcourse change.
Hope this clears ur doubt
Rate if it does...
Cheers!!!!!!!!!!!!!!!!!!!!!!!!!
