Errors in Measurement

A force 'F' is applied on a square plate of side 'L'. If the percentage error in determining 'L' is 3% and that in 'F' is 2% then the percentage error in determining the pressure is

Show answer and solution

Answer: (d)

  1. Pressure P=FL2P = \frac{F}{L^2}, so ΔPP=ΔFF+2ΔLL\frac{\Delta P}{P} = \frac{\Delta F}{F} + 2\frac{\Delta L}{L}
  2. =2%+2(3%)=8%= 2\% + 2(3\%) = 8\%
  3. So the answer is (d) 8%8\%.
