What is the fractional decrease in the value of free-fall acceleration g for a particle when it is lifted from the surface to an elevation `h`? `(h lt lt R)`

Answer

B, D

Explanation

`g = (Gm)/(R^(2))`
`rArr (dg)/(dR) = (-2Gm)/(R^(3))`
`rArr (dg)/(h) = (-2Gm)/(R^(2)) * (1)/(2)`
`rArr (dg)/(g) = - 2((h)/(R))`
