A portal frame shown in figure (not drawn to scale) has a hinge support at joint $\mathrm{P}$ and a roller support at joint $R$. A point load of $50 \mathrm{kN}$ is acting at joint $\mathrm{R}$ in the horizontal direction. The flexural rigidity, $E I,$ of each member is $10^{6} \mathrm{kNm}^{2}$. Under the applied load, the horizontal displacement (in $\mathrm{mm},$ round off to 1 decimal place ) of joint $\mathrm{R}$ would be
