A force \(F\) is applied on a square plate of length \(L\). If the percentage error in the determination of \(L\) is \(3 \%\) and in \(F\) is \(4 \%\), then permissible error in the calculation of pressure is
- A \(13 \%\)
- B \(10 \%\)
- C \(7 \%\)
- D \(12 \%\)
Answer & Solution
Correct Answer
(B) \(10 \%\)
Step-by-step Solution
Detailed explanation
Given, Percentage error in length \(=3 \%\) Percentage error in force \(=4 \%\) We know that, Pressure, \(\quad P=\frac{F}{A}\) Area of square \(=(L)^2\)…
