Question

A body weighs 10 kgs on the equator. At the poles, it is likely to weigh

1. A. 10 kgs
2. B. Less than 10 kgs
3. C. More than 10 kgs (Correct answer)
4. D. 0

Correct Answer

Option C — More than 10 kgs

Detailed Solution & Explanation

The correct answer is More than 10 kgs.

Key Points

• A body weighs more at the poles than at the equator because: (1) Earth is slightly flattened at the poles, so the poles are closer to Earth's center, increasing gravitational pull.
• (2) The centrifugal effect of Earth's rotation is maximum at the equator, reducing effective gravity.
• Thus, 10 kg at the equator weighs slightly more than 10 kg at the poles.
