A) \[1000\,\,N\,\,s\]
B) \[250\,\,N\,\,s\]
C) \[500\,\,N\,\,s\]
D) \[2000\,\,N\,\,s\]
Correct Answer: D
Solution :
\[F=\frac{m(v-u)}{t},\,\,200=\frac{2(v-u)}{10}\]\[\Rightarrow \]\[(v-u)=1000\,\,m\,\,{{s}^{-1}}\]Change in momentum\[=m(v-u)\]\[=2\times (1000)=2000\,\,N\,\,s\]You need to login to perform this action.
