A) \[2\times {{10}^{3}}N\]
B) \[5\times {{10}^{4}}N\]
C) \[2\times {{10}^{6}}N\]
D) \[2\times {{10}^{8}}N\]
Correct Answer: C
Solution :
Given, \[m=1000\text{ }kg\] Initial velocity \[(u)=0\] The rate at which fuel is consumed\[\left( \frac{m}{t} \right)=40\,kg/s\] Final velocity \[(v)=5\times {{10}^{4}}\text{ }m/s.\text{ }F=?\] we know, \[F=v\times \frac{m}{t}\] \[\Rightarrow \]\[F=40\times 5\times {{10}^{4}}=2\times {{10}^{6}}N\]You need to login to perform this action.
