Satellite A has a mass of 1000kg. Satellite B has a mass of 2000kg. BOth are in orbit 250km above the surface of the earth. Satellite A will have an orbital speed that is ____ satellite B.
1. the same as.
2. four times that of.
3. twice that of.
Not really sure on this. I originally said half that of and it was incorrect.
The gravitational force between two masses is 36 N. If the distance between the mass is decreased to one-half its original value, the force of gravity will be:
1. 144 N
2. 9 N
3. 18 N
My original answer was 72 N, and I forgot to square the radius if I remember correctly. So I am fairly confident the answer is 144 N.
Thanks
