Question A:

In the $3-$dimensional cartesian space, the region havinig $x<mn>0</mn>$ consists of a perfect conductor, while that having $x>0$ consists of a dielectric insterial with $lo{n}_1=4.$ If there is a surface charge of ${}_8=2n\frac{C}{m}{m}^2$ on the interface between the two thiedia, ainswer the following parts of the question.
