A satellite used in a cellular telephone network has a mass of 2020 kg and is in a circular orbit at a height of 660 km above the surface of the earth.
A) What is the gravitational force Fgrav on the satellite? Take the gravitational constant to be G = 6.67x10^−11 1 N⋅m^2/kg^2, the mass of the earth to be me = 5.971024 kg , and the radius of the Earth to be re = 6.38x10^6m. Express your answer in newtons.
B) 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/s^2.
