Question

A geo-stationary satellite is orbiting the earth at a height of 6R above the surface of earth, R being the radius of earth. The time period of another satellite at a height of 2.5R from the surface of earth is :

10 hr
$(6 / \sqrt{2})$ hr
6 hr
$6 \sqrt{2}$ hr

The correct answer is: $6 square root of 2$ hr
