A) \[{{54}^{o}}\]
B) \[{{125}^{o}}\]
C) \[{{27}^{o}}\]
D) \[{{18}^{o}}\]
Correct Answer: C
Solution :
Range \[=\frac{{{u}^{2}}\sin \,2\theta }{g}\] \[\therefore \] \[560=\frac{{{(82)}^{2}}\sin \,2\theta }{10}\] or \[\sin \,2\theta =0.832\,\,\,[\sin \,{{56.30}^{o}}=0.832]\] \[\Rightarrow \] \[\theta \approx {{27}^{o}}\]You need to login to perform this action.
