The orbital speed of a satellite depends on its mass.
Answer: B
False. Orbital speed does not depend on the satellite's mass.
Equating gravitational and centripetal force, \[\frac{GMm}{r^2} = \frac{mv^2}{r} \Rightarrow v = \sqrt{\frac{GM}{r}}\] The satellite's mass \(m\) cancels, so it depends only on the earth's mass and the radius of the orbit.
