defence exam Army Havildar SAC Mock Test Series 2025 Physics Mechanical Properties of Solids Elastic moduli
An increase of 0.1% in the length of a wire of cross-section 10-6 m2 causes tension of 1 × 100 N in the wire. The Young's modulus of the material of the wire is:
1
1012 N/m2
2
1011 N/m2
3
1010 N/m2
4
109 N/m2
