Question

Calculate the effective value of g , the acceleration of gravity, at 6800 km , above the Earth's surface.

Answer 1

9.79395 m/s²
2.44228 m/s²
Explanation:
m = Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 km
a) at h = 6400 m

g = 9.79395 m/s²
b) at h = 6400000 m

g = 2.44228 m/s² I believe
