Question

If the Earth were to spin faster, acceleration due to gravity at the poles

• A. increases
• B. decreases
• C. remains the same
• D. depends on how fast it spins

Hint:

At the poles, the rotational speed of the Earth does not affect gravity because the centripetal force is zero at these points.

Answer 1

The Correct Option is C

The acceleration due to gravity at the poles remains the same regardless of Earth's rotation speed. This is because, at the poles, the centripetal acceleration caused by the Earth's rotation is zero. Therefore, the only factor affecting gravity at the poles is the Earth's mass, not its rotational speed. Thus, the correct answer is (C).
