Question

A body is weighed at the poles and at the equator. The weight:

• A. at the equator it will be more than at the poles
• B. at the poles it will be greater than at the equator
• C. at the poles it will be equal to the weight at the equator
• D. depends upon the object

Answer 1

The correct option is B at the poles it will be greater than at the equator

The earth is not a perfect sphere. It bugles at its centre. So, it's distance from the centre towards the equator is comparatively more than the poles. The gravity keeps on changing as we move from one place to another. But it is maximum at the place where it is nearer to the centre. As a result, the gravity is more at the poles and least at the equator.

So Weight = $mg$, at poles the value of g is highest so at poles it will weight more than equator.
