A) \[{{R}^{2}}=2\,{{h}_{1}}{{h}_{2}}\]
B) \[{{R}^{2}}=16\,{{h}_{1}}{{h}_{2}}\]
C) \[{{R}^{2}}=4\,{{h}_{1}}{{h}_{2}}\]
D) \[{{R}^{2}}=\,{{h}_{1}}{{h}_{2}}\]
Correct Answer: B
Solution :
For same range angle of projection will be\[\theta \And 90-\theta \] \[R=\frac{{{u}^{2}}2\sin \theta \cos \theta }{g}\] \[{{h}_{1}}=\frac{{{u}^{2}}{{\sin }^{2}}\theta }{g}\] \[{{h}_{2}}=\frac{{{u}^{2}}{{\sin }^{2}}(90-\theta )}{g}\] \[\frac{{{R}^{2}}}{{{h}_{1}}{{h}_{2}}}=16\]You need to login to perform this action.
