A force F is applied on a square plate of side L. If the percentage error in the determination of L is 2% and that in F is 4%. What is the permissible error in pressure?

Options:

Answer:

Solution:

$P = \frac{F}{L^{2}}$

Permissible % error in $P = (%$ error in $F) + 2 \times (%$ error in $L) = 4 % + 2 \times 2 % = 8 %$
