Question

When the center of gravity of a body lies below the point of suspension or support, the body is said to be in ________ equilibrium. Fill in the blank.

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

Answer 1

The correct option is A Stable

When the center of gravity of a body lies below point of suspension or support, the body is said to be in stable equilibrium. For example a book lying on a table is in stable equilibrium.A book lying on a horizontal surface is an example of stable equilibrium. If the book is lifted from one edge and then allowed to fall, it will come back to its original position.
Other examples of stable equilibrium are bodies lying on the floor such as chair, table etc.
