Correct Answer - Option 2 : decreases continuously
CONCEPT:
-
Gravitational acceleration: An acceleration that an object receives due to the force of gravity acting on it.
It is calculated by using the formula:
\(g = {GM\over R^2}\)
where g is the gravitational acceleration, G is the gravitational constant, M is the mass of the earth and R is the radius of the earth.
- The radius of the earth is less at the poles compared to the equator.
EXPLANATION:
Gravitational Acceleration is given by:
\(g = {GM\over R^2}\)
- The earth is not a perfect sphere. The poles are closer to the earth.
As we move from pole to equator the radius R increases, So \(g = {GM\over R^2}\) decreases.
- So g at the pole is more than at the equator.
- Hence the correct answer is option 2.
