Question

Pressure due an object on the ground is least at

• A. Equator
• B. Center of earth
• C. Above the earth's surface
• D. Poles

Answer 1

The correct option is A

Equator

P=hdg

Earth is not a perfect sphere. Its radius at equator is greater than poles. Acceleration due to gravity is inversely proportional to the square of its radius. So, the acceleration due to gravity is greatest at poles. Hence, from relation, W = mg, it is clear that weight is highest at the poles.
