    A tank of height 5 m is full of water. There is a hole of cross-sectional area 1 cm2 in its bottom, The volume of water that will come out from this hole per second is (g = 10 m/s2)

    A)                  10-3 m3/s                            

    B)                  10-4 m3 /s

    C)                  10m3 /s                               

    D)                  10-2 m3 /s

    Correct Answer: C

    Solution :

                     \[h\rho g=\frac{1}{2}\rho \left( \frac{{{v}^{2}}}{{{a}^{2}}} \right)\]                 \[{{V}^{2}}=2hg{{a}^{2}}\]                 \[{{V}^{2}}=2\times 5\times 10\times {{(1)}^{2}}\]                 \[{{V}^{2}}=100\]                 \[V=10\,{{m}^{3}}/s\]
