    A gun fires two bullets at \[60{}^\circ \] and \[30{}^\circ \] with horizontal. The bullets strike at some horizontal distance. The ratio of maximum height for the two bullets is in the ratio of

    A) 2 : 1                 

    B)        3 : 1

    C) 4 : 1                 

    D)        1 : 1

    Correct Answer: B

    Solution :

    [b] The bullets are fired at the same initial speed \[\frac{H}{H'}=\frac{{{u}^{2}}\,{{\sin }^{2}}\,60{}^\circ }{2\,g}\times \frac{2\,g}{{{u}^{2}}\,{{\sin }^{2}}\,30{}^\circ }=\frac{{{\sin }^{2}}\,60{}^\circ }{{{\sin }^{2}}\,30{}^\circ }\]       \[=\frac{{{(\sqrt{3}/2)}^{2}}}{{{(1/2)}^{2}}}=\frac{3}{1}\]
