## Homework Statement

I want to find the period of the satellite.

## Homework Equations

mg = mv^2/r

## The Attempt at a Solution

I derive the equation

mg = mv^2/r

v = sqrt(gr)

v = ωr and ω = 2π/T

T = 2π/ω = 2πr/v

Then, T = 2πr/sqrt(gr)

But the answer is 2πr/R * sqrt(r/g). I don't know why? Is there anyone can give an explanation to me why it is not correct.
