The maximum and minimum distances of a comet from the Sun are 1.6 $\times$ 1012 m and 8.0 $\times$ 1010 m respectively. If the speed of the comet at the nearest point is 6 $\times$ 104 ms$-$1, the speed at the farthest point is :

Question

The maximum and minimum distances of a comet from the Sun are 1.6 $\times$ 10¹² m and 8.0 $\times$ 10¹⁰ m respectively. If the speed of the comet at the nearest point is 6 $\times$ 10⁴ ms^$-$1, the speed at the farthest point is :

3.0 $\times$ 10³ m/s

6.0 $\times$ 10³ m/s

1.5 $\times$ 10³ m/s

4.5 $\times$ 10³ m/s
