A gun fires two bullets at $6 0^{\circ}$ and $3 0^{\circ}$ with horizontal. The bullets strike at some horizontal distance. The ratio of maximum height for the two bullets is in the ratio of

Options:

Answer:

Solution:

The bullets are fired at the same initial speed $\frac{H}{H ^{'}} = \frac{u ^{2} s i n ^{2} 6 0 ^{\circ}}{2 g} \times \frac{2 g}{u ^{2} s i n ^{2} 3 0 ^{\circ}} = \frac{s i n ^{2} 6 0 ^{\circ}}{s i n ^{2} 3 0 ^{\circ}} = \frac{( 3 /2 ) ^{2}}{( 1/2 ) ^{2}} = \frac{3}{1}$
