A satellite used in a cellular telephone network has a mass of 2410 kg and is in a circular orbit at a height of 730 km above the surface of the earth.
What is the gravitational force Fᵣₐᵥ on the satellite?
take the gravitational constant to be g = 6.67×10⁻¹¹ n ⋅ m²/kg² , the mass of the earth to be 5.97×10²⁴ kg , and the radius of the earth to be 6.38×10⁶ m.
Fᵣₐᵥ = 1.83x10⁴ N
What fraction is this of the satellite's weight at the surface of the earth?
Take the free-fall acceleration at the surface of the earth to be g = 9.80 m/s²
