In the relation $F=G\times \frac{M\times m}{d^2}$, the quantity $G$:
(a) depends on the value of g at the place of observation
(b) is used only when the earth is one of the two masses
(c) is the greatest on the surface of the earth
(d) is of the same value irrespective of the place of observation
In the relation, $F=G\times \frac{M\times m}{d^2}$, the quantity $G$ is always constant at each place.
So, option (d) is correct.
