The dimension of Young's Modulus is:
Correct answer: C. ML-1T-2
- A. M2L-1T2
- B. ML-1T-1
- C. ML-1T-2
- D. ML-2T-2
Explanation
Young's modulus is the slope of the initial section of the curve (i.e. m in y = mx + b). When a material reaches a certain stress, the material will begin to deform. It is up to a point where the structure of the material is stretching and not deforming. Unit of Young's Modulus =N/m2=kgm/s2m2=ms2kg=ML−1T−2.
