The pressure on a square plate is measured by measuring the force on the plate. If the maximum error in the measurement of force and length are respectively $4%$ and $2%$ , then the maximum error in the measurement of pressure is

Options:

Answer:

Solution:

$Pressure = \frac{force}{area} = \frac{F}{L ^{2}} ∴ \frac{Δ p}{p} = \frac{Δ F}{F} + \frac{2Δ L}{L} = 4% + 2 (2%)$ or percentage error, $= 8%$ \
