    The pressure increases on the fluid in a syringe when a nurse applies a force of 42 N to the syringes circular piston, which has a radius of 1.1 cm.

    A)  \[1.1\times {{10}^{5}}Pa\]                          

    B)  \[11\times {{10}^{5}}Pa\]

    C)  \[1.1\times {{10}^{7}}Pa\]                          

    D)  \[1.1\times {{10}^{1}}Pa\]

    Correct Answer: A

    Solution :

                    Force applied = 42 N                 radius = 1.1 cm                 Pressure \[=\frac{F}{A}\]                                 \[=\frac{42}{3.14\times {{(1.1\times {{10}^{-2}})}^{2}}}\]                                 \[=1.1\times {{10}^{5}}Pa\].
