  • A
    greater than the orbital speed of Earth
  • ✓
    less then the orbital speed of Earth
  • C
    zero
  • D
    equal to the orbital speed of Earth
✓

Answer

Correct option: B.
less then the orbital speed of Earth
less then the orbital speed of Earth
Hint :
$\frac{v_j}{v_e}=\frac{r_e}{r_j}$, as $r_j>r_e$ therefore $v_j
