## Question

### Solution

Correct option is

If the period of revolution of a satellite about the earth be T. then

Where h is the height of the satellite from earth’s surface.

The satellite is revolving just above the earth, hence h is negligible compared to Re.

where ρ is the density of the earth. Thus

Which is a universal constant. To determine its value,
