alleryIn uniform gravity the centre of gravity coincides with the:
ACentre of mass
BFulcrum point
CRotation axis
DChosen origin
Answer & Solution
Correct answer: A. Centre of mass
1. g is the same for every particle of a small body.
2. The gravitational torque then vanishes at the centre of mass.
3. So the two centres coincide.
