  • question_answer
    The range of a particle when launched at an angle of \[{{15}^{o}}\] with the horizontal is 1.5 km. What is the range of the projectile when launched at an angle of \[{{45}^{o}}\] to the horizontal                                  [CPMT 1982]

    A)             1.5 km

    B)               3.0 km

    C)             6.0 km

    D)               0.75 km

    Correct Answer: B

    Solution :

                    \[{{R}_{15{}^\circ }}=\frac{{{u}^{2}}\sin (2\times 15{}^\circ )}{g}\]\[=\frac{{{u}^{2}}}{2g}=1.5\,km\]            \[{{R}_{45{}^\circ }}=\frac{{{u}^{2}}\sin (2\times 45{}^\circ )}{g}=\frac{{{u}^{2}}}{g}=1.5\times 2=3\,km\]
