    The value of atmospheric pressure on the surface of earth at sea level is nearly Take density of mercury\[=\text{ }13600\text{ }kg/{{m}^{3}}\]; density of water \[=\text{ }1000\text{ }kg/{{m}^{3}}\]

    A)  \[{{10}^{5}}\text{ }Pa\]

    B)  \[{{10}^{3}}\text{ }Pa\]

    C)  \[{{10}^{1}}\text{ }Pa\]               

    D)  \[{{10}^{4}}\text{ }Pa\]

    Correct Answer: A

    Solution :

      The value of atmospheric pressure on the surface of earth at sea level is \[P=hdg=\frac{76}{100}\times 13600\times 1000\,={{10}^{5}}Pa\] The correct answer is A.
