The orbital speed of Jupiter is (A) greater than the orbital speed of earth. (B) lesser than the orbital speed of earth. (C) equal to the orbital speed of earth. (D) Zero.
As we know that, Orbital velocity, $v \propto \frac{1}{\sqrt{r}}$ As Jupiter is farther than Earth from Sun, so its orbital speed is less than orbital speed of Earth.
GRAVITATION
Gravitation
Earth and Jupiter both orbit the sun in orbits that are approximately constant speed circular motion (about the sun – with Jupiter of course further from the sun and with a much greater mass than Earth). Taking the orbits to be exactly circular, for which planet is the magnitude of its acceleration the greatest? a) Earth b) Jupiter c) Actually, the magnitude of the acceleration for both is zero due to the orbits being constant speed orbits.
