A body has its centre of maas at the origin. The x-coordinates of the particles

A

all positive

B

al negative

C

zero

D

positive for some particles and negative for some particles

Text Solution

Verified by Experts

The correct Answer is:
D
The x coordinate of the centre of mass of a system of particles is given by
`x=(sum_(i=1)^(i=n)m_(i)x_(i))/(M)`
As x is at the origin x = 0
`:. X_(i)` may be positive for some particles and negative for some particles
