Question

explain any two factor affecting the value of g​

Answer 1

here

The following are the factors that affect the value of g :

(i) Shape of the earth: The earth is not perfectly spherical in shape. It is slightly flattened at the poles and bulgy towards the equator. The value of g is maximum (9.83 m/s2) at the poles as the polar radius is minimum, while it is minimum (9.78 m/s2) at the equator as the equatorial radius is maximum.

(ii) Altitude: As the height (h) above the earth’s surface increases, the value of g decreases. It varies by a value of begin math size 12px style 1 over open parentheses straight R plus straight h close parentheses squared end style, where R is radius of the Earth.

(iii) Depth: In the interior of the Earth, on an average, the value of g is less than that at the earth’s surface. As the depth below the earth’s surface increases, the value of g decreases and finally it becomes zero at the centre of the Earth.

Answer 2

mass of the earth and radius of the earth
