A) \[{{\tan }^{-1}}\left( \frac{3}{2} \right)\]
B) \[{{\tan }^{-1}}\left( \frac{2}{3} \right)\]
C) \[{{\tan }^{-1}}\left( \frac{1}{2} \right)\]
D) \[{{\tan }^{-1}}\left( \frac{3}{4} \right)\]
Correct Answer: B
Solution :
We know that range of a projectile \[R=\frac{{{U}^{2}}\sin 2\theta }{g}\] Here \[R=6+18=24\] \[\therefore \] \[\frac{{{u}^{2}}\sin 2\theta }{g}=24\] ? (i)You need to login to perform this action.
