The value of acceleration due to gravity
$(a)$. is same on equator and pole?
$(b)$. is least on poles
$(c)$. is least on equator
$(d)$. increases from pole to equator

AcademicPhysicsNCERTClass 9

We know the expression for gravitational acceleration $g=G\frac{M}{r^2}$

Here we come to know that the value of gravitational acceleration is inversely proportional to the distance between the center and the surface of the earth.

On the poles, the distance between the center and the surface of the earth is the least, so $g$ has a greater value on the poles. While on equators the distance between the surface of the ground and the center is greater, so on the equator value of $g$ is the least.

So, option $(c)$ is correct.
