Question 8

A planet is in a circular orbit of radius $R\,$ around a star. The orbital period of the planet is $T$ . Which expression gives the magnitude of the centripetal acceleration of the planet?

$4π2RT2\frac{4\pi^2 R}{T^2}$

$4πR2T\frac{4\pi R^2}{T}$

$2πRT2\frac{2\pi R}{T^2}$

$4π2R2T\frac{4\pi^2 R^2}{T}$
