    A box of mass 10 kg has a base area of \[1\text{ }{{m}^{2}}\]. What is the pressure exerted by it on the ground? (Take 1 kg wt = 10 N)

    A)  50 Pa                                   

    B)  70 Pa

    C)  100 Pa                 

    D)  120 Pa

    Correct Answer: C

    Solution :

      F = weight of box \[=10\text{ }kg\text{ }wt=10\times 10\text{ }N\] \[=100\text{ }N,\text{ }A=1\text{ }{{m}^{2}}\] \[P=\frac{F}{A}=\frac{100}{1}Pa=100Pa\] The correct answer is C.
