A difficult satellite problem

  1. Jun 15, 2010 #1
    1. The problem statement, all variables and given/known data
    A satellite is orbiting above the earth. By what factor must the orbital radius be changed in order to double the period of the orbit? (Mearth = 5.98 x 1024kg, Rearth = 6.36x106m)

    3. The attempt at a solution
    i got 1.59 by T1/T2=(r1/r2)^3/2 so r1/r2=(T1/T2) ^2/3 so 2^2/3 =1.59 but i have no clue if i did that right
