A) \[1%\]
B) \[2\,%\]
C) \[6\,%\]
D) \[8\,%\]
Correct Answer: D
Solution :
\[P=\frac{F}{A}=\frac{F}{{{l}^{2}}}\] so maximum error in pressure (P) \[{{\left( \frac{\Delta P}{P}\times 100 \right)}_{\max }}\,=\,\,\frac{\Delta F}{F}\times 100+2\frac{\Delta l}{l}\times 100\] \[=4% + 2 \times 2% = 8%\]You need to login to perform this action.
