The change in the value of g at a height h above the surface of earth is the same as at a depth X below its surface then

A

`X=h^(2)`

B

`X=h`

C

`X=2h`

D

`X=0.2h`.

Text Solution

Verified by Experts

The correct Answer is:
C
`g_(d)=g_(h)`
`g(1-(X)/(R )) = g(1-(2h)/(R ))`
`rArr X=2h`.
Thus correct choice is (c ).
