365101 A ray \(P Q\) incident on the refracting face \(B A\) is refracted in the prism \(B A C\) as shown in the figure and emerges from the other refracting face \(A C\) as \(R S\), such that \(A Q=A R\). If the angle of prism \(A=60^{\circ}\) and the refractive index of the material of prism is \(\sqrt{3}\), then the angle of deviation of the ray is:
