In Fig-1, there are two infinite planes A and B, parallel to the YZ plane. Their surface charge densities are σA = −47nC/m2 and σB = 28nC/m2. The separation between the planes A and B is d = 10m.
a) Find the net electric field in unit vector notation in the region I, II, and III shown in Fig-1.
b) Now, we place a conducting spherical shell of radius R=0.1d in between the planes. The spherical shell conductor carries a surface charge density σ = −25μC/m2. The coordinates of the center(d/2,d/2,0), P1 (4d/5, d/2, 0) and P2 (d/2, d/4, 0). Find the net electric field at points P1 and P2 in unit vector notation.
