Q 24 During Searle s experiment zero of the Vernier scale lies between 3 20 x 10 2 m and 3 25 x 10 2 m of the main scale The 20th division of the Vernier scale exactly coincides with one of the main scale divisions When an additional load of 2 kg is applied to the wire the zero of the Vernier scale still lies between 3 20 x 10 2 m and 3 25 x 10 2 m of the main scale but now 45th division of Vernier scale coincides with one of the main scale divisions The length of the thin metallic wire is 2 m and its cross sectional area is 8 x 10 7 m The least count of the Vernier scale is 1 0 x 10 5 m The maximum percentage error in the Young s modu of the wir la 001
