Question

Why the weight of an individual is greater at poles than at the equator?

Answer 1

'Centrifugal force' due to the spinning lowers your body weight by about 0.4 per cent at the equator relative to its weight at the poles. The Earth's spin also causes the planet to bulge, so that at the equator you're about 21km further from the Earth's centre of gravity and so weigh around 0.1 per cent less.
