As we go from the equator to the poles, the value of `g`

Options

A. remains the same
B. decreases
C. increases
D. decreases upto latitude of `45^(@)`

Answer

C

Explanation

Since g = `(GM_(e))/(R_(e)^(2))` for earth.
At poles the earth is slightly flattened. It means that the radius of earth at poles is slightely less in comparison to radius at equator. So from the above expression, the value of .g. at poles is greater in comparison to value of .g. at equator .
