Circular Motion question
explain why a spring balance with a mass M attached would give different readings at the North Pole and at the Equator. Estimate the difference in the readings for a mass 10kg given that the radius of Earth is 6400km. Assume Earth is a sphere of uniform density.
I don't udnerstand why it would be different if you're assuming that its a sphere. is it to do with distance from the sun?

The earth rotates. Think centripetal force.
