In a Searle s experiment following are the observations Least count of micrometer of Searle s apparatus 0 001 cm Pitch of screw gauge 0 1 cm Number of divisions on circular scale 100 There is no zero error in screw gauge While measuring diameter of wire the linear scale reads 0 mm and 50th division on circular scale coincides with the reference line Scale used for measuring length has a least count of 0 1 cm Length of wire recorded by scale is 110 cm Following load w versus extension 1 graph is made using experimental observations x10 m 1 25 40 50 60 17 Young s modulus of the wire is a 25 x 10 N m b 2 50 x 10 N m c 0 56 x 10 N m d 5 60 x 10 1 N m w N 18 Maximum percentage error in the measurement Young s modulus is around 100 b 1
