Question

The value of gravitational acceleration is:

a. highest at poles b. highest at equator c. lowest at poles d. lowest at equator.​

Answer 1

Answer:

The centrifugal force for the spinning of earth is maximum at the equator and vanishes at the poles. Thus, the gravitational acceleration (g) is minimum at the equator and it is maximum at the poles.

Explanation:

Answer 2

The value of gravitational acceleration is a. highest at poles.

Gravitational acceleration is denoted by g and it can be found out by

$g=\frac{GM_{p}^{2}}{r^{2}}$

• Thus, gravitational acceleration is inversely proportional to the square of the distance between the two bodies.
• The distance of the centre of earth and pole is less as compared to that of the equator. This is because earth is not perfectly spherical in shape. It is little flat at the poles.
• Thus, the value of gravitational acceleration is highest at the poles.
• The distance of other points from the centre of earth is same, so they will have same value of gravitational acceleration except for poles.
