A) \[{{90}^{o}}\]
B) \[{{180}^{o}}\]
C) \[{{60}^{o}}\]
D) \[{{75}^{o}}\]
Correct Answer: A
Solution :
Range\[=\frac{{{u}^{2}}\sin 2\theta }{g}\]; when \[\theta =90{}^\circ \], \[R=0\] i.e. the body will fall at the point of projection after completing one dimensional motion under gravity.You need to login to perform this action.
