Solution

The correct option is B Point A is closer to the Equator than Point A.
The tangential velocity of Earth at the Equator is 1674.4 km per hour. It varies according to the location. It decreases as we move away from the Equator. This is because the distance between a point on the Earth and the axis of the Earth decreases near the poles. Thus, point A is relatively closer to the equator than point B as the tangential velocity at point A is greater than point B.
