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 uncertainty of 0.05 mm at a load of exactly 1.0 kg. The student also measures the diameter of the wire to be 0.4 mm with an uncertainty of 0.01 mm. Take g = 9.8 m/s (exact). The Young's modulus obtained from the reading is (A) (2.0 0.3) x 10 N/m (C) (2.00.1) x 10 N/m (B) (2.00.2) x 10 N/m (D) (2.0 0.05) x 10 N/m A student performs an experiment to determine the Young's modulus of a wire, exactly 2 m long, by Searle's method.
