In a Searl's experiment the diameter of a wire as measured by a Micrometer of least count 0.001 cm is 0.5 cm. The length measured by a scale of least count 0.1 cm is 110.0 cm. When a weight of 50 N is suspended from the wire, the extension is measured to be 0.125 cm by a micrometer of least count 0.001 cm. Find the maximum error in the measurement of Young's modulus of the material of the wire from these data.
