Question

A satellite has a mass of 99kg and is located at2.0x106m above the surface of Earth.
(a) What is the potential energy associated with the satellite atthis location? (answer in Joules) (b) What is the magnitude of the gravitational force on thesatellite? (answer in Newtons) A satellite has a mass of 99kg and is located at2.0x106m above the surface of Earth.

Explanation / Answer

given that m = 99kg ME= 5.98 * 1024kg radius of satilite = earth radius + altitude = r =(6.37+2.0) 106m potential energy = U = - GMEm/r where G = 6.67 * 10-11N.m2/kg2 force = F = GMEm/r2 plug in values F = ------N plug in values F = ------N
