Question

As we go from the equator of the earth to pole of the earth, the value of acceleration due to gravity

• A. Decreases.
• B. Remains same.
• C. Decreases up to latitude of 45° and increases thereafter.
• D. Increases.

Hint:

Gravity is maximum at the poles and minimum at the equator due to the earth’s rotation and its shape.

Answer 1

The Correct Option is D

Step 1: Gravity variation with latitude.
The acceleration due to gravity \( g \) is highest at the poles and lowest at the equator. This is because of the earth’s shape and rotational motion.
Step 2: Gravity at the poles and equator.
At the equator, the centrifugal force due to the earth’s rotation partially counteracts gravity, making \( g \) lower. At the poles, there is no centrifugal force acting on the body, so \( g \) is at its maximum.
Step 3: Conclusion.
As we move from the equator to the poles, the value of acceleration due to gravity increases, so the correct answer is (D).
