Gravitation
The time period of an earth satellite in circular orbit is independent of
-
the mass of the satellite
-
radius of its orbit
-
both the mass and radius of the orbit
-
neither the mass of the satellite nor the radius of its orbit.
A.
the mass of the satellite
Time period of satellite
where R + h = orbital radius of satellite,
Me = mass of earth Thus, time period does not depend on the mass of the satellite.
