A force of $\displaystyle -\mathrm{P} \hat{\mathrm{k}}$ acts on the origin of the coordinate system. The torque about the point $\displaystyle (2,-3)$ is $\displaystyle \mathrm{P}(\mathrm{a} \hat{\mathrm{i}}+\mathrm{b} \hat{\mathrm{j}})$, The ratio of $\displaystyle \frac{a}{b}$ is $\displaystyle \frac{x}{2}$. The value of $\displaystyle x$ is -
