Multiple choice

Medium 1 has the electrical permittivity $\xi_1$= 1.5 $\xi_0$ farad/m and occupies the region to the left of x = 0 plane. Medium 2 has the electrical permittivity $\xi_2$ = 2.5 $\xi_0$ farad/m and occupies the region to the right of x = 0 plane. If E1 in medium 1 is E1 = (2ux -3uy + 1uz) volt/m, then E2 in medium 2 is

  1. (2.0ux - 7.5uy + 2.5uz) volt/m

  2. (2.0ux - 2.0uy + 0.6uz) volt/m

  3. (1.2ux - 3.0uy + 1.0uz) volt/m

  4. (1.2ux - 2.0uy + 0.6uz) volt/m
