A semi-circular bar of radius $\text{R m}$, in a vertical plane, is fixed at the end $G$, as shown in the figure. A horizontal load of magnitude $\text{P kN}$ is applied at the end $H$. The magnitude of the axial force, shear force, and bending moment at point $Q$ for $\theta = 45^{\circ}$, respectively, are

- $\frac{P}{\sqrt{2}}\:kN, \frac{P}{\sqrt{2}}\:kN$, and $\frac{PR}{\sqrt{2}}\:kNm$
- $\frac{P}{\sqrt{2}}\:kN, \frac{P}{\sqrt{2}}\:kN$, and $0 \:kNm$
- $0\:kN, \frac{P}{\sqrt{2}}\:kN$, and $\frac{PR}{\sqrt{2}} \:kNm$
- $\frac{P}{\sqrt{2}}\:kN,0\:kN$, and $\frac{PR}{\sqrt{2}} \:kNm$
