A) 5000 Pa, 25,000 Pa
B) 6000 Pa, 20,000 Pa
C) 4000 Pa, 15,000 Pa
D) 10000 Pa, 10,000 Pa
Correct Answer: A
Solution :
(i) Force (F) = Weight of brick \[=2.5\text{ }kg\text{ }wt=2.5\times 10\text{ }N=25\text{ }N\] Area of base\[=10\times 5\text{ }c{{m}^{2}}=50\text{ }{{m}^{2}}=\frac{50}{10000}{{m}^{2}}\] \[\therefore \] \[Pressure=\frac{F}{A}=\frac{25}{50}\times 10,000\,Pa\] \[=5000\text{ }Pa\]You need to login to perform this action.
