A spacecraft is in a stable circular orbit around Mars. The orbit has radius R R\,R and period TTT.
Which expression gives the magnitude of the centripetal acceleration of the spacecraft?
2πR2T2\frac{2\pi R^2}{T^2}T22πR2
4π2RT2\frac{4\pi^2 R}{T^2}T24π2R
2πRT\frac{2\pi R}{T}T2πR
4πRT2\frac{4\pi R}{T^2}T24πR
