The centre of gravity is where the total gravitational torque is:
AKept constant
BKept positive
CExactly zero
DAt its largest
Answer & Solution
Correct answer: C. Exactly zero
1. Gravity acts on every particle of an extended body.
2. Their turning effects balance about one particular point.
3. That point is the centre of gravity.
