Question
Transcribed Image Text:An 1800 kg satellite is in a highly elliptical Molniya orbit.
At its farthest point, it's orbital radius is 58000 km.
Compute the gravitational force acting on it.
Use F = Weight = G*M*m/R^2
G = 66.73*10^(-12) m^3/(kg*s^2)
M = mass of the Earth = 5.972*10^24 kg
(Earth's radius is 6378 km at the equator. However, this is not needed for this question.)
