A satellite is orbiting the earth in a circular orbit of radius $r.$ Its
kinetic energy varies as $r$
angular momentum varies as $\frac{1}{\sqrt r}$
linear momentum varies as $\frac{1}{r}$
frequency of revolution varies as $\frac{1}{r^{3/2}}$
Write the Kepler law of period (Kepler’s third law) for planetary motion.
State and prove Kepler’s second law (Law of Areas) of planetary motion.
The time period of a satellite of earth is $5$ hours. If the separation between the earth and the satellite is increased to four times the previous value, the new time period will become ......... $hours$
A body revolved around the sun $27$ times faster then the earth what is the ratio of their radii
The relative uncertainty in the period of a sateilite orbiting around the earth is $10^{-2}$. If the relative uncertainty in the radius of the orbit is negligible, the relative uncertainty in the mass of the earth is
