As we learnt

 

Variation of 'g' due to shape of earth -

 

Equitorial radius is about 21 km longer than polar radius.

Requator > Rpole

R_{e}\rightarrow Radius of equator

R_{p}\rightarrow Radius of pole
 

- wherein

gpole > gequator

g_{p}=g_{e}+0.018m/s^{2}

Weight increases as body is taken from equator to pole

 

 As we know,

g\: \: \alpha \: \: \frac{1}{R^2}

Here, R_e>R_p\: \: then\: \: g_p>g_e

g_{p}=g_{e}+0.018m/s^{2}

Hence weight  at poles is more as compared to earth equator.
