Why is the weight of a body at the poles more than the weight at the equator ? Explain.

Explanation

As `g=GM"/"R^2` and the value of R at the poles is less than that the equator, so g at poles is greater than that g at the equator. Now, `g_(p) gt g_e`, hence `mg_(p) gt g_e` i.e., the weight of a body at the poles is more than the weight at the equator.
