A) 2 : 1
B) 1 : 2
C) 1 : 1
D) 2 : 3
Correct Answer: C
Solution :
[c] For angle\[(45{}^\circ -\theta )\], \[R=\frac{{{u}^{2}}\sin (90{}^\circ -2\theta )}{g}=\frac{{{u}^{2}}\cos 2\theta }{g}\] For angle\[(45{}^\circ +\theta )\], \[R=\frac{{{u}^{2}}\sin (90{}^\circ +2\theta )}{g}=\frac{{{u}^{2}}\cos 2\theta }{g}\]You need to login to perform this action.
