Vedclass · Answer

(A) The dimension of energy density is given by: $	ext{Energy density} = \frac{	ext{Energy}}{	ext{Volume}} = \frac{[ML^2T^{-2}]}{[L^3]} = [ML^{-1}T^{-2}]$. Young's modulus $(Y)$ is defined as: $Y = \frac{	ext{Stress}}{	ext{Strain}} = \frac{	ext{Force/Area}}{	ext{Change in length/Original length}}$. Since strain is dimensionless,the dimensions of Young's modulus are the same as stress: $[Y] = \frac{[MLT^{-2}]}{[L^2]} = [ML^{-1}T^{-2}]$. Refractive index and dielectric constant are dimensionless quantities. Magnetic field has dimensions $[MT^{-2}A^{-1}]$. Thus,energy density and Young's modulus have the same dimensions.
