a) Algebraic sum of moments of masses about centre of mass is zero
b) For small bodies centre of mass coincides with centre of gravity
c) Position of centre of mass depends on co-ordinate system
d) Position of centre of mass is independent of mass distribution

View answer and explanation

Correct option: A

a and b are correct

Option A (a and b are correct) is correct because the algebraic sum of moments of masses about the center of mass is zero, and for small bodies, the center of mass and center of gravity coincide.
