SUMMARY
The magnitude of the acceleration due to gravity at a height of 1.20 × 106 m above the Earth's surface can be calculated using the formula g' = (Re2/r2) * g, where Re is the Earth's radius and g is the standard acceleration due to gravity at the surface. The correct calculation involves determining the total distance r from the center of the Earth, which is the sum of the Earth's radius and the height above the surface. The initial attempt using g = (G * ME * m) / r2 yielded an incorrect value due to not accounting for the Earth's radius in the total distance.
