a.)calculate at what height above the earth's surface a satellite must be placed if it is to remain over the same gerographical point on the equator of the earth. b.)what is the velocity of such a satellite?(adsbygoogle = window.adsbygoogle || []).push({});

i have no idea how to do the question, but i know it has to do with these equations:

Fcent.=Fgrav.

m(v^2)/r=GMm/(r^2)

because my book doesn't have answers for this question, i don't know the answer for this question.
