A thin prism $\displaystyle \mathrm{P}_1$ with angle $\displaystyle 4^{\circ}$ made of glass having refractive index $\displaystyle 1.54$ , is combined with another thin prism $\displaystyle \mathrm{P}_2$ made of glass having refractive index $\displaystyle 1.72$ to get dispersion without deviation. The angle of the prism $\displaystyle \mathrm{P}_2$ in degrees is
