Q. The orbital speed of Jupiter is
A) Greater than the orbital speed of earth
B) Less than the orbital speed of earth
C) Equal to the orbital speed of earth
D) Zero
Explanation
(b) Orbital radius of Jupiter > Orbital radius of Earth
$\frac{v_{J}}{v_{e}} = \frac{r_{e}}{r_{J}}$. As $r_{J} > r_{e}$ therefore $v_{J} < v_{e}$
