The dimension of young’s modulus,E is given by
- MLT\(^{-1}\)
- MT\(^{-2}\)
-
ML\(^{-1}\)T\(^{-2}\)
- M\(^{-1}\)T
The correct answer is: C
Explanation
Young's modulus E is given by the formula: E = \(\frac{\text{STRESS}}{\text{STRAIN}}\)
Stress = \(\frac{Force}{Area}\)
Dimension of force = MLT\(^{-2}\)
Dimension of Area = L\(^2\)
Dimension of strain = 1(dimensionless)
E = \(\frac{MLT^{-1}}{L^2}\) = ML\(^{-1}\)T\(^{-2}\)
