Question
The value of acceleration due to gravity
(a) is same on equator and poles
(b) is least on poles
(c) is least on equator
(d) increases from pole to equator
Solution
The correct answer is (c) is least on equator.
Here's why:
-
The Earth is not a perfect sphere but an oblate spheroid, meaning it's slightly flattened at the poles and bulging at the equator.
-
Because of this shape, the distance from the center of the Earth to the surface is greater at the equator than at the poles.
-
The force of gravity decreases with distance, so the further surface of the Earth at the equator experiences a slightly weaker gravitational pull.
-
Therefore, the acceleration due to gravity is least at the equator.
-
So, the statement (c) is correct. The value of acceleration due to gravity is least on the equator.
