The time period of satellite is given by,
where, r is the radius of the orbit.
When the satellite just revolves around the earth, then r = R
Therefore,
Time period of satellite near the surface of the earth is,



where, r is the radius of the orbit.
When the satellite just revolves around the earth, then r = R
Therefore,
Time period of satellite near the surface of the earth is,
