Physics

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
