SUMMARY
The gravitational field strength formula, g = GM/r², is essential for calculating the gravitational force at a specific height above the Earth's surface. In this discussion, the mass of the Earth is established as 5.98E24 kg, and the gravitational constant G is 6.67E-11 N(m/kg)². To find the gravitational field strength at a height of 350 km, the total distance from the Earth's center must be converted to meters, resulting in a radius of 7,000,000 meters. The calculated gravitational field strength at this height is approximately 9 N/kg.
