PHY 101 Mechanical Equilibrium and Rotational Dynamics Objective Question

Question

When a body acted upon by gravity is suspended from a single point, where is its centre of gravity located relative to the point of suspension?
Options
A Always directly below the point of suspension.
B Always directly above the point of suspension.
C Always at or directly above/below the point of suspension.
Correct Answer
D At the point of suspension itself.
Correct Answer

Option C is the correct answer.

Detailed Explanation

When a body is suspended from a single point, it will come to rest with its centre of gravity located somewhere on a vertical line that passes through the point of suspension. Depending on the body's shape and the suspension point, the centre of gravity could be directly below or directly above the point of suspension (in stable or unstable equilibrium).

Hint

Consider how a freely suspended object orients itself under the influence of gravity.
