Question

How does value of 'g' vary as we go;
1) above the earth surface?
2) below the earth surface? ​

Answer 1

Answer:

So we can say that as we move upwards, then h increases, and since it is associated with a negative sign, the value of gh decreases and becomes less than g. Therefore gravity varies with height gh=g(1−2hR), and it decreases as we move above the surface of the earth.

Answer 2

Answer:

1)the value of g decreases

2)the value of g increases
