If the change in the value of `g` at a height `h` above the surface of earth is the same as at a depth `d` below it (both `h` and `d` are much smaller than the radius of the earth), then

A

`d=(h)/(2)`

B

`d=(3h)/2`

C

d=2h

D

d=h

Text Solution

Verified by Experts

The correct Answer is:
C
`g[1-d/R]=g[1-(2h)/R] ` or d =2h
