Question

Mark correct option or options.

• A. Only equatorial orbit are stable for a satellite
• B. Escape velocity does not depend upon angle of projection
• C. A communication satellite rotates in a direction from west to east
• D. All of the above

Answer 1

The correct option is D All of the above

$\left(i\right)$ Satellite is most stable in its quitorial orbit.

$\left(ii\right)$ Escape velocity, $v_o=\sqrt{2gR}$ is independent of angle of projection.

$\left(iii\right)$ A communication satellite rotates in the direction from west to east.
