A) \[\frac{1}{500}{{m}^{2}}\]
B) \[\frac{1}{5000}{{m}^{2}}\]
C) \[\frac{1}{5}{{m}^{2}}\]
D) \[\frac{1}{50}{{m}^{2}}\]
Correct Answer: D
Solution :
\[P=6000\text{ }Pa;\text{ }F=120\text{ }N;\text{ }A=?\] We know that \[P=\frac{F}{A}\] \[\Rightarrow \]\[A=\frac{F}{P}=\frac{120}{6000}{{m}^{2}}=\frac{1}{50}{{m}^{2}}\] The correct answer is D.
