2.0\times10^{7}\,\text{m}

with a period of

8.0\,\text{h}

. The radius of planet R is

. From these data, the acceleration due to gravity at the surface of planet R is closest to (a)

19.6\,\text{m}\,\text{s}^{-2}

(b)

9.8\,\text{m}\,\text{s}^{-2}

(c)

13.9\,\text{m}\,\text{s}^{-2}

(d)

15.2\,\text{m}\,\text{s}^{-2}
