    A large number of bullets are fired in all directions with the same speed v. What is the maximum area on the ground on which these bullets will spread?

    A) \[\frac{\pi {{v}^{2}}}{g}\]                               

    B) \[\frac{\pi {{v}^{4}}}{{{g}^{2}}}\]  

    C) \[{{\pi }^{2}}\frac{{{v}^{4}}}{{{g}^{2}}}\]

    D) \[\frac{{{\pi }^{2}}{{v}^{4}}}{{{g}^{2}}}\]

    Correct Answer: B

    Solution :

    Maximum possible horizontal range \[={{v}^{2}}/g\] Maximum possible area of the circle \[=\pi {{\left( \frac{{{v}^{2}}}{g} \right)}^{2}}=\frac{\pi {{v}^{4}}}{{{g}^{2}}}\]
