Earth Satellites
PHXI08:GRAVITATION

359779 Two satellites \(S_{1}\) and \(S_{2}\) revolve round a planet in the same direction in circular orbits. Their periods of revolution are 1 hour and 8 hours respectively. The radius of \(S_{1}\) is \({10^4}\;km\). The velocity of \(S_{2}\) with respect to \(S_{1}\) will be-

1 \(\pi /3 \times {10^4}\;km/hr\)
2 \(\pi \times {10^4}\;km/hr\)
3 \(\pi /2 \times {10^4}\;km/hr\)
4 \(2\pi \times {10^4}\;km/hr\)

359780 If the law of gravitation be such that the force of attraction between two particles vary inversely as the \(5/{2^{th}}\) power of their separation, then the graph of orbital velocity \(v_{0}\) plotted against the distance \(r\) of a satellite from the earth's centre on a log-log scale is shown along side. The slope of line will be
