The answer is below.

Work Step by Step

G is the gravitational constant in the equation for the gravitational force, so it is the same no matter where in the earth a person is. However, g is an approximation of $\frac{Gm_{planet}}{r_{planet}}$ that makes calculations faster, so it changes based on which planet a person is on. Also, g is an acceleration, making it a vector, while G is a scalar.
