An expression of energy density is given by $\displaystyle u=\frac{\alpha}{\beta} \sin \left(\frac{\alpha x}{k \mathrm{t}}\right)$, where $\displaystyle \alpha, \beta$ are constants, $\displaystyle x$ is displacement, $\displaystyle k$ is Boltzmann constant and t is the temperature. The dimensions of $\displaystyle \beta$ will be :
