GATE EC 2003 Set 1 Q84 — Maxwell's Equations

Medium $1$ has the electrical permittivity $\varepsilon_{1}=1.5 \varepsilon_{0}$ farad $/ \mathrm{m}$ and occupies the region to the left of $x=0$ plane. Medium $2$ has the electrical permittivity $\varepsilon_{2}=2.5 \varepsilon_{0}$ farad $/ \mathrm{m}$ and occupies the region to the right of $x=0$ plane. If $\mathrm{E}_{1}$ in medium $1$ is $E_{1}=\left(2 u_{x}-3 u_{y}+1 u_{z}\right)$ volt $/ m$, then $E_{2}$ in medium $2$ is
