If the radius of the Earth were to increase while keeping its mass constant, what would happen to the value of g? (2023)

Step 1: Understand that 'g' is the acceleration due to gravity at the surface of the Earth.
Step 2: Know that 'g' is calculated using the formula g = G * M / r^2, where G is the gravitational constant, M is the mass of the Earth, and r is the radius of the Earth.
Step 3: Recognize that if the radius (r) increases and the mass (M) stays the same, the value of r^2 (the radius squared) will also increase.
Step 4: Since g is inversely proportional to r^2, an increase in r^2 means that g will decrease.
Step 5: Conclude that if the radius of the Earth increases while keeping its mass constant, the value of g will decrease.
