A student performs an experiment to determine the Young’s modulus of a wire, exactly 2 m long, by Searle’s method. In a particular reading, the student measures the extension in the length of the wire to be 0.8 mm with an uncertainity of 0.05 mm at a load of exactly 1.0 kg. The student also measures the diameter of the wire
