Vedclass · Answer

(C) The unit $Dyne/cm^2$ represents force per unit area. Pressure is defined as force per unit area $(P = F/A)$,so its unit is $Dyne/cm^2$ in the $CGS$ system. Stress is also defined as restoring force per unit area,so its unit is $Dyne/cm^2$. Young's modulus is defined as the ratio of stress to strain. Since strain is a dimensionless quantity (ratio of change in length to original length),the unit of Young's modulus is the same as that of stress,which is $Dyne/cm^2$. Strain is defined as the ratio of change in dimension to the original dimension (e.g.,$\Delta L/L$). As it is a ratio of two similar physical quantities,it is a dimensionless quantity and has no units. Therefore,$Dyne/cm^2$ is not a unit of strain.
