A person will get more quantity of matter in kg-wt at:

A)  poles                                   

B)  at latitude of 60°

C)  equator                                              

D)  satellite

Correct Answer: C

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 = mg, therefore a person will get more quantity of matter in kg-wt at equator.
