A) \[\theta ={{\tan }^{-1}}(1)\]
B) \[\theta ={{\tan }^{-1}}\](4)
C) \[\theta ={{\tan }^{-1}}\](3)
D) \[\theta ={{\tan }^{-1}}\](2)
Correct Answer: B
Solution :
Let a particle be projected with initial velocity u at an angle\[\theta \]with the horizontal. Then, range (R) of projectile is \[R=\frac{{{u}^{2}}\sin 2\theta }{g}\] ?.. (i)You need to login to perform this action.
