Question

In a non-uniform gravitational field, how does the Centre of Gravity relate to the Centre of Mass?

Options

• They are always the same

• c.g. is slightly higher than c.m.

• c.g. is slightly lower than c.m.

• They are completely unrelated

Answer 1

c.g. is slightly lower than c.m.

Explanation:

In non-uniform fields, gravity is stronger at lower positions, so c.g. shifts slightly downward compared to c.m.
