A) \[\theta ={{\tan }^{-1}}6\]
B) \[\theta ={{\tan }^{-1}}2\]
C) \[\theta ={{\tan }^{-1}}25.92\]
D) \[\theta ={{\tan }^{-1}}4\]
Correct Answer: B
Solution :
\[v=72\,km/hour=20\,m/\sec \] \[\theta ={{\tan }^{-1}}\left( \frac{{{v}^{2}}}{rg} \right)={{\tan }^{-1}}\left( \frac{20\times 20}{20\times 10} \right)={{\tan }^{-1}}(2)\]You need to login to perform this action.
