निम्न में से कौन सा यंग-गुणांक का मात्रक नहींं है
1 न्यूटन-मी\(^{-1}\)
2 न्यूटन-मी\(^{-2}\)
3 डाईन-से.मी.\(^{-2}\)
4 मेगा-पास्कल
Explanation:
Young's modulus \(\quad Y =\frac{\text { Stress }}{\text { Strain }}\) As we know, strain is a dimensionless quantity whereas stress is defined as force per unit area. Stress has units as \(Nm ^{-2}\) (SI unit), Dyne \(cm ^{-2}\) (cgs unit) or Pascal \(( P a)\). As Young's modulus has same unit as that of stress, thus \(Nm ^{-1}\) is not a unit of Young's modulus.
