A) \[1000\text{ }c{{m}^{2}}\]
B) \[3000\text{ }c{{m}^{2}}\]
C) \[4000\text{ }c{{m}^{2}}\]
D) \[2000\text{ }c{{m}^{2}}\]
Correct Answer: D
Solution :
\[F=300\text{ }N,\text{ }P=1500\text{ }Pa,\text{ }A=?\] We know that \[P=\frac{F}{A}\] \[\Rightarrow \] \[A=\frac{F}{P}=\frac{300}{1500}=\frac{1}{5}{{m}^{2}}\] \[=\frac{1}{5}\times 10,000c{{m}^{2}}=2000c{{m}^{2}}\] The correct answer is D.You need to login to perform this action.
