Problem
A communication satellite is shifted from an initial circular orbit of radius r1 to a new circular orbit of radius r2 around Earth.
(i) If r2=1.60r1, by what factor does the satellite’s orbital period change? Express the factor correct to three significant figures.
(ii) In a separate operation, the satellite’s period is required to become four times its original value. Calculate the percentage increase in orbital radius necessary to achieve this change.
