Question

7) The value of gravitational acceleration (g) is ..
a) highest at the poles
b) highest at the equator
c) same everywhere on the surface of the earth
d) lowest at the poles​

Answer 1

• highest at the poles

Explanation:

the value of acceleration due to gravity is highest at the pole i.e (9.832 m/s square) because surface of earth is flatter at pole hence radius is smallest, therefore according to formula" g= GM/r square" if radius will decrease then (g) will increase

Answer 2

Option d) The value of gravitational acceleration (g) is highest at the poles.

• The formula used to calculate gravitational acceleration is g = GM/R².
• Therefore gravitational acceleration is inversely proportional to the radius of Earth.
• The shape of Earth is not spherical, i.e. it is flatter at the poles and bulges at the equator.
• Thus, the radius of Earth at the poles is lesser than the equator.
• According to the formula, if the radius is lesser then the gravitational acceleration value is more.
• Hence the value of g at the poles is the highest.
