In an experiment on the determination of young's Modulus of a wire by Searle's method , following data is available: Normal length of the wire (L) = 110 cm Diameter of the wire (d) = 0.01 cm Elongation in the wire (l) = 0.125 cm This elongation is for a tension of 50 N . The least counts for corresponding quantities are 0.01 cm , 0.00005 cm, and 0.001 cm , respectively. Calculate the maximum error in calculating the value of Young's modulus (Y) .
