Take CBT

Question

What is the centre of gravity of a body?
Options
A The point where the body's mass is evenly distributed.
B The point where the entire weight of the body appears to act.
Correct Answer
C The point around which the body would naturally rotate.
D The geometric centre of the body.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The centre of gravity is defined as the point through which the total weight of a body can be considered to act, regardless of the body's orientation. It is the point where the force of gravity effectively acts on the body.

Hint

Think of the single point you would need to support an object to balance it perfectly against gravity.
