    A diver is \[20\,\,m\] below the water surface. Given that the density of the water is\[1000\,\,kg\,\,{{m}^{-3}}\], what is the pressure exerted by the water on the diver? (Take\[g=10\,\,m{{s}^{-2}}\])

    A) \[10,000Pa\]      

    B)        \[1,00,000Pa\]

    C) \[2,00,000Pa\]     

    D)        \[3,00,000Pa\]

    Correct Answer: C

    Solution :

    \[\rho gh=(1,000)(10)(20)=2,00,000\,\,Pa\]
