A system in neutral equilibrium has an equilibrium that is:
ARestored after displacement
BReversed by displacement
CIndependent of displacement
DDestroyed by displacement
Answer & Solution
Correct answer: C. Independent of displacement
1. The three kinds of equilibrium differ in what a nudge does.
2. A system is in neutral equilibrium under one specific condition.
3. Its equilibrium is independent of displacements from its original position.
4. Stable and unstable equilibrium both respond to displacement.
