    Energy and Young's modulus have the same dimensions, comment.

    Answer:

                    No, it is not true as their dimensions are different.                 \[Energy=\left[ {{M}^{1}}{{L}^{2}}{{T}^{-2}} \right]\] Young's modulus = \[\frac{F/a}{\Delta L/L}=\frac{ML{{T}^{-2}}/{{L}^{2}}}{1}=\left[ {{M}^{1}}{{L}^{-1}}{{T}^{-2}} \right]\]
