The pressure on a square plate is measured by measuring the force acting on the plate and length of the sides of the plate. The maximum error in the measurement of force and length are respectively \(4 \%\) and \(2 \%\), the percentage error in the measurement of pressure is
- A 1%
- B 2%
- C 6%
- D 8%
Answer & Solution
Correct Answer
(D) 8%
Step-by-step Solution
Detailed explanation
\( P = \frac{F}{L^2} \) \( \frac{\Delta P}{P} \% = \frac{\Delta F}{F} \% + 2 \frac{\Delta L}{L} \% \)
