Answer:
Yes, the value of g affected by the radius.
Explanation:
The formula for the force of gravity of 2 objects is
[tex]F_{gravity} = G\frac{m_{1}m_{2}}{r^2}[/tex], where m1 and m2 are the masses of the 2 objects, r is the radius, and G is the gravitational constant, which is approximately [tex]6.67 \cdot 10^{-11}[/tex].
Therefore, as the radius if bigger, the force of gravity is going to be smaller exponentially.
