Question

The value of acceleration due to gravity of earth:

• A. is maximum at the equator
• B. is minimum at the equator
• C. is the same at the equator and the poles
• D. is zero at the poles

Answer 1

Answer: (B)

is minimum at the equator

Answer is B.
The value of g changes from place to place due to the elliptical shape of the Earth and the rotation of the Earth. Due to the shape of the Earth.
Hence, it is inversely proportional to the square of the radius.
Therefore, it is least at the equator and maximum at the poles, since the equatorial radius (6378.2 km) is more than the polar radius (6356.8 km).
That is, acceleration due to gravity is maximum at the poles and minimum at the equator.
