Find the orbit radius of an Earth satellite in a circular orbit if the period if 1d.
I'm at a dead end. So far I have;
r^3 = (GMT^2) / (4(pi)^2)
r^3 = (6.67*10^(-11) * 6*10^(24)) / (4 * pi^2)
and I get
r = 21642
The book says 42.2Mm. I'm only off by a couple of million meters, hahaha.
Where am I going wrong?
Thanks,
Bernie
