The value of the acceleration due to gravity is
g1 at a height h = $${R \over 2}$$ (R = radius of the earth) from the surface of the earth. It is again equal
to g1 at a depth d below the surface of the
earth. The ratio $$\left( {{d \over R}} \right)$$ equals :
- A$${5 \over 9}$$
- B$${1 \over 9}$$
- C$${7 \over 9}$$
- D$${4 \over 9}$$
