The dimensional formula of the product of two physical quantities P and Q is  $\left[{\text{ML}}^{\text{2}}{\text{T}}^{-\text{2}}\right]$.

            The dimensional formula of $\frac{\text{P}}{\text{Q}}$ is $\left[{\text{ML}}^{\text{0}}{\text{T}}^{-\text{2}}\right]$. Then which physical quantities are represented

            by P and Q
