Question

a man weighs more at the poles than at the equator . give scientific reason

Answer 1

since g at poles is greater than g at equator
w=mg
when g changez the weight also changes

Answer 2

'Centrifugal force' due to the spinning lowers your body weight by about 0.4 per cent at the equator relative to itsweight 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.
