Question

As a body moves from the equator to the poles, the value of g experienced by the body

• A. decreases
• B. increases
• C. remains unchanged
• D. first decreases then increases

Answer 1

The correct option is B increases

The shape of the earth is not perfectly spherical. It is flattened at the poles and bulged out at the equator. So earth has more radius at the equator in compare to at poles.

As we know $g=\frac{GM}{R^2}$, where G: Universal gravity constant, R: Radius of earth.

Because radius at equator is more, acceleration due to gravity will be more at pole.

Hence when a body moves from the equator to the poles, the value of g experienced by the body increases.
