A

poles

B

at latitude of $6 0^{\circ}$

C

equator

D

satellite

Solution:

The earth is not a solid sphere but is somewhat flattened at the poles and bulged at equator, its equitorial radius is $21 km$ larger than its polar radius.
Since, $g = \frac{GM}{R ^{2}}$
Hence, value of $g$ is least at equator and maximum at poles.
Also, $W = m g$ , therefore a person will get more quantity of matter in $k g$ -wt at equator.
