PhysicsEasysingle choice

The orbital velocity of an artificial satellite in a circular orbit just above the earth's surface is $v$ . For a satellite orbiting at an altitude of half of the earth's radius, the orbital velocity is

Options:

Answer:

Solution:

We know that $v_{0} = \sqrt{\frac{G M}{R}}$ for a satellite at at altitude $\frac{R}{2}$ ,

$v_{1} = \sqrt{\frac{G M}{(R + \frac{R}{2})}}$

therefore $\frac{v_{1}}{v} = \sqrt{\frac{2}{3}}$
