    What is the magnitude of force required in newton's to produce a pressure of 27500 Pa on an area of \[200\text{ }c{{m}^{2}}\]?

    A)  650 N                                   

    B)  750 N

    C)  550 N                                   

    D)  450 N

    Correct Answer: C

    Solution :

      \[A=200\,c{{m}^{2}}=\frac{200}{10000}{{m}^{2}}\] \[P=27500\text{ }Pa,\]                   \[F=?\] \[\therefore \]We know that \[P=\frac{F}{A}\] \[\Rightarrow \] \[F=P\times A=27500\times \frac{200}{10000}N=550\,N\] The correct answer is C.
