Per NCERT §6.8.2, the CENTRE OF GRAVITY of an extended body in a UNIFORM gravitational field coincides with which point?
AThe centre of mass
BAlways the geometric centre
CThe highest mass point
DThe lowest point of the body
Answer & Solution
Correct answer: A. The centre of mass
NCERT §6.8.2: in uniform g, CG = CM. In non-uniform fields they differ.
