Question

Explain the variation of G with depth from the Earth's surface​

Answer 1

1. The value of acceleration due  to gravity, g, is not constant at all the places on the surface of the  earth.
2. Since the radius  of the earth at the poles is minimum, the value of g is maximum  at the poles. Again, the radius of earth is maximum at the equator,  so the value of g is minimum at the equator.
3. As we go up from the surface of the earth, the distance from the centre of the earth increases,  and hence the value of g decreases.
4. The value of g also decreases as we go down  inside the earth.
5. The value of acceleration due to gravity, g, is maximum on the  surface of the earth, it decreases on going above  the surface of earth or on going inside the surface  of the earth.

Answer 2

Answer:

As profundity increment, g' diminishes. It is exceptionally fascinating to realize that speed increase because of gravity is most extreme on the outer layer of the Earth yet diminishes when we go either vertically or descending

Explanation:

Accept the profundity of the mine as d. To compute g' at a profundity d, consider the accompanying focuses. The piece of the Earth which is over the span (Re – d) don't add to the acceleration.Read more on Sarthaks.com - https://www.sarthaks.com/907607/clarify the-variety of-g-with-profundity from-the-earths-surface
