Homework Equations
T^2=constant * r^3
The Attempt at a Solution
First of all I compute the constant whit the values of the first planet:
(108)^2 = const. * (1'8*10^12)^3 → const= 2*10^-33
Then, I compute the period of the second planet:
T^2 = 2*10^-33 * (9*10^11)^3 → T = √1458 = 38,18 s
This solution doesn't apear in the results I have to choose. What do I have wrong?
Thank you!
