The work functions of two metals $\displaystyle \left(\mathrm{M}_{\mathrm{A}}\right.$ and $\displaystyle \left.\mathrm{M}_{\mathrm{B}}\right)$ are in the $\displaystyle 1: 2$ ratio. When these metals are exposed to photons of energy $\displaystyle 6$ eV , the kinetic energy of liberated electrons of $\displaystyle \mathrm{M}_{\mathrm{A}}: \mathrm{M}_{\mathrm{B}}$ is in the ratio of $\displaystyle 2.642$ : 1. The work functions (in eV) of $\displaystyle \mathrm{M}_{\mathrm{A}}$ and $\displaystyle M_B$ are respectively.
