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

Answer:

                As \[g=GM/{{R}^{2}}\] and the value of R at the poles is less than that at the equator, so g at poles is greater that g at the equator. Now, as  \[{{g}_{p}}>{{g}_{e}},\] hence \[m{{g}_{p}}>m{{g}_{e}}\]i.e., the weight of a body at the poles is more than the weight at the equator.
