Question

When the centre of gravity of a body lies at the point of suspension or support, the body is said to be in _____ equilibrium. Fill in the blank.

• A. Stable equilibrium
• B. Unstable equilibrium
• C. Neutral equilibrium
• D. All of the above

Answer 1

Answer: (C)

Neutral equilibrium

When the center of gravity of a body lies at the point of suspension or support, the body is said to be in neutral equilibrium. Example: rolling ball.If the ball is pushed slightly to roll, it will neither come back to its original nor it will roll forward rather it will remain at rest. This type of equilibrium is called neutral equilibrium.
