The diameter of a wire is measured with a screw gauge of least count 0.001 cm and is found to be 0.08 cm. Its length, measured with a scale of least count 0.1 cm, is 150 cm. When a load of 100 N is applied, the extension is 0.5 cm, measured with an instrument of least count 0.001 cm. Ignoring any uncertainty in the applied load, the absolute error in the calculated Young's modulus is α×10⁹ N·m⁻². What is α?
