If an artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of the escape velocity from the earth. The height of the satellite above the surface of the earth is

Options:

Answer:

Solution:

$V_{0} = \frac{V e}{2} = \frac{1}{2} \sqrt{\frac{2 G M}{R}} \Rightarrow \sqrt{\frac{G m}{2 R}}$ ...(i)

$V_{0} = \sqrt{\frac{G m}{R + h}}$ ...(ii)

Compare (i) & (ii) ; $h = R$
