A system that stays balanced while rotating at constant angular velocity satisfies:
AOnly the first one
BNo condition at all
CThe second condition
DNeither condition
Answer & Solution
Correct answer: C. The second condition
1. Equilibrium does not require the object to be motionless.
2. The second condition necessary to achieve equilibrium involves avoiding accelerated rotation.
3. That means maintaining a constant angular velocity.
4. So constant rotation is consistent with the second condition being met.
