# Which of the following does not have the same dimension?

##### ANSWER

Pressure, stress, Young's modulus

##### SOLUTION
Dimension of pressure $=\left[\dfrac{Force}{Area}\right]=\dfrac{MLT^{-2}}{L^2}=ML^{-1}T^{-2}$
Dimension of stress$=\left[\dfrac{force}{Area} \right]=\cfrac{MLT^{-2}}{L^2}=ML^{-1}T^{-2}$
Dimension of young modulus $E=\dfrac{Stress}{strain}=\left[\dfrac{force/Area}{ strain}\right]=ML^{-1}T^{-2}$
Option B
