Question

As we go from the equator towards the poles, the value of $g$

• A. Remains the same
• B. Decreases
• C. Increases
• D. Decreases upto the altitude of ${45}^o$ and then increases

Answer 1

The correct option is C Increases

Acceleration due to gravity at earth's surface is g = $\frac{Gm}{r^2}$ where r is the radius of earth, M is mass of the earth and G is universal gravitational constant. Hence the relation between gravity and radius is inversely proportional to each other. Thus the value of g on earth is maximum at poles and goes on decreasing as we go towards the equator.
