The orbital velocity of an artificial satellite in a circular orbit just above the earth's surface is \( \mathrm{v}_{0} \).
\( \mathrm{P} \) The orbital velocity of satellite orbiting at an

W altitude of double the radius of earth is:
(1) \( \sqrt{3} v_{0} \)
(2) \( \sqrt{2} v_{0} \)
(3) \( \frac{v_{0}}{\sqrt{3}} \)
(4) \( \frac{v_{0}}{\sqrt{2}} \)
