Question

Quizplus · Accepted Answer

An unstable equilibrium is a situation in which a small change in an object's position or configuration causes it to move significantly away from its original position. This means that after the system is disturbed slightly from its equilibrium position, it moves farther away from its original position. Therefore, option B is the correct answer. Options A, C, and D describe a stable equilibrium, neutral equilibrium, and fixed equilibrium, respectively.
