The acceleration of a body due to the attraction of hte earth (radius R) at a distace 2R from the surface of the earth is (g = acceleration due to gravity at the surface of the earth )

Options

A. `(g)/(9)`
B. `(g)/(3)`
C. `(g)/(4)`
D. g

Answer

A

Explanation

`(g.)/( g) = ((R)/( R + h))^(2) = ((R)/(R + 2R))^(2) = (1)/(9):. g. = (g)/(9)`
