MCQ
The orbital speed of Jupiter is
- AGreater than the orbital speed of earth
- ✓Less than the orbital speed of earth
- CEqual to the orbital speed of earth
- DZero
✓
Answer
Correct option: B.
Less than the orbital speed of earth
b
(b) Orbital radius of Jupiter > Orbital radius of Earth
(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 ${v_J} < {v_e}$
