Homework Statement



a satellite has a period of T and orbital radius R. If you wish to increase the period to 8T what must the new orbital radius be. (answer= 4T, I just don't know how they got it)

Homework Equations


R1 cubed/ T1 squared = R2 cubed/ T2 squared



The Attempt at a Solution


The answer i got was 8

You've got 1. so far. 2 and 3?
 
That sounds reasonable.

Check calculation again.
