28.What is the relation between the orbital velocity and the radius of the orbit for a given planet? [A] greater the radius of orbit, lesser will be the orbital velocity [B] greater the radius of orbit, greater will be the orbital velocity [C] orbital velocity is independent of radius of orbit [D] None of the above Show Answer
As seen in the equation v = SQRT(G * Mcentral / R), the mass of the central body (earth) and the radius of the orbit affect orbital speed. The orbital radius is in turn dependent upon the height of the satellite above the earth.
