Problem

A satellite is to be placed in a circular orbit so that the centripetal (orbital) acceleration acting on it is

0.30\,g

, where

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

at Earth’s surface. Estimate the altitude

h

above Earth’s surface required for this mission. (Take Earth’s radius

R_{\rm E}=6.4\times10^{6}\,\text{m}

.) Choose the nearest value. (a)

1.6\times10^{6}\,\text{m}

(b)

5.3\times10^{6}\,\text{m}

(c)

3.2\times10^{6}\,\text{m}

(d)

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