Answer:
M=gr^2/G, where is the acceleration due to gravity, r is the distance between the center of the object and the center of the Earth, and G is the gravitational constant.
Explanation:
The reason why G is in the denominator is because it is a constant that is used to convert the units of the other variables in the equation. The numerator contains the variables that are specific to the object being measured, while the denominator contains the constant that is used to convert those variables into the correct units.
In this case, r^2 and g are in the numerator because they are specific to the object being measured. The distance between the center of the object and the center of the Earth ® and the acceleration due to gravity (g) are both important factors in determining the mass of the object.
