I am stuck on these problems i really don't know how to do them.So can anyone please help me. Can you explain how to do these questions.
A 620 kg satellite above the Earth's surface experiences a gravitational field strength of 4.5 N/kg.
a) Knowing the gravitational field strength at Earth's surface abd Earth's radius, how far above the Earth's surface is the satellite? (Use ratio and proportion.
b) Determine the magnitude of the gravitational force on the satellite.
I know for b) i need a) but i don't seem to get the right answer for a.
for a this is wat i do.
gs=GMs/Rs^2
ge=GMe/Re^2
then i get g s/g e = Ms/Me x (Re/Rs)^2
But i don't get the right answer for it.
