## Question

### Solution

Correct option is

35830

Let h be the height of the satellite above the earth. The period of revolution of the satellite is

If the period of revolution of the satellite be equal to the period of the axial rotation (24 hours) of the earth (and the satellite be revolving from west to east), then the satellite will appear stationary relative to the earth.

Substituting this value in eq. (i), we get
