The centre of mass of a system of particles is at the origin. It follows that

A

the number of particle to the righ of the origin is equal to the number of particles to the left

B

the total mass of the particles to the right of the origin is same as the total mass to the left of theorigin

C

the number of particles on X-axis should be equal to the number of particles on Y-axis

D

if there is a particle on the positive X-axis, there must be at least one particle on the negative X-axis.
