Question

e) The figure shows two semi-infinite media. One of the media is glass (x <0) and the other medium is a conductor (x >0). The two media have a common boundary at x -0. The electric field in glass is given by E, (4-3x +8x')ä, and the relative permitivity of glass is s,-2.25 From the given information we may conclude that the surface charge density equals: on the boundary 1) 46 2)-%, 3)-7.75E0 4) 9e, 5)-4є0 6) 2.256, (4-3x +8x2) 2 Glass Conductor e, = 2.25 x=0

I think it should be 9epslon
