Homework Help: Orbital radius vs period question

  1. May 24, 2010 #1
    1. The problem statement, all variables and given/known data

    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 dont know how they got it)

    2. Relevant equations
    R1 cubed/ T1 squared = R2 cubed/ T2 squared



    3. The attempt at a solution
    The answer i got was 8
