A) \[117.6\text{ kg}{{\text{s}}^{-1}}\]
B) \[58.6\text{ kg}{{\text{s}}^{-1}}\]
C) \[6\text{ kg}{{\text{s}}^{-1}}\]
D) \[76.4\text{ kg}{{\text{s}}^{-1}}\]
Correct Answer: C
Solution :
[c] \[\text{Thrust }=\frac{udM}{dt}=mg\] \[\Rightarrow \frac{dM}{dt}=\frac{mg}{u}=\frac{600\times 10}{1000}=6\text{ kg}{{\text{s}}^{-1}}\]
