The acceleration due to gravity at a hei...

The acceleration due to gravity at a height `1km` above the earth is the same as at a depth `d` below the surface of earth. Then :

`d = 1 km`

`d = (3)/(2) km`

`d = 2 km`

`d = (1)/(2) km`

Text Solution

Verified by Experts

`g_(h) = g_(d)`
`g (1 - (2 h)/(Re)) = g (1 - (d)/(Re))`
`d = 2 h 2 km`
