A satellite has a mass of 94 kg and is located at 1.96 106 m above the surface of Earth.

(a) What is the potential energy associated with the satellite at this location? (b) What is the magnitude of the gravitational force on the satellite?

potential energy = mgh

= 94* 10 * 106 = 99640 J

F= G*m1*m2/ r^2

F= (6.67*10^-11)*94 *6*10^24/ 106^2

F=0.33 *10^13 N

A=99640 J

B=0.33 *10^13 N

sorry dear i tried my best.....
dont know where was the problem....

this one 106 = 10^6

Jun 8th, 2015

no dear
10^6= 1000000

Jun 8th, 2015

I know but did you use it as this 10^6 or 106

Jun 8th, 2015

as 10^6
