    A long cylindrical drum is filled with water. Two small holes are made on the side of the drum as shown in the figure. Find the depth of the liquid in the drum if the ranges of water from the holes are equal-

    A) 0.3 m

    B) 0.5 m

    C) 0.7 m

    D) 0.9 m

    Correct Answer: A

    Solution :

    \[{{(Range)}_{1}}={{(Range)}_{2}}\] \[\sqrt{2g(\ell -0.1)}\sqrt{\frac{2\times 0.1}{g}}\] \[=\sqrt{2g(\ell -0.2)}\sqrt{\frac{2\times 0.2}{g}}\] \[\ell =0.3\]
