Centre of mass doubt - HCV page 141 Example 9.2

VITEEE 2015 Guidance › General Physics questions › Centre of mass doubt - HCV page 141 Example 9.2

Now my doubt is, if we consider C as the origin then centre of mass comes on CD at a distance L/4 from C. i.e., F â‰¡ (0, L/4)

But what if we consider A as the origin...

In this case we get, F â‰¡ (L/2, L/4)

Can't we choose the origin as per our convenience... and won't it give the same result...??

If this doubt is silly ... then i can't help as i m a beginner... Just started studying centre of mass today itself :P

obviously the coordinates of the C.O.M will change as you have changed the origin. the new answer is wrt to the new origin.

I am also a begineer
So at rishabh c.o.m depends on the origin??

You have got the same result in the second case as well.
The coordinates are different because you shifted the origin, but the physical location of the COM remains the same.
