An infinitely wide, charged, non-conducting slab with a non-zero thickness is centered over the xy plane as described .It has a thickness of 2a. The volume charge density is z dependent and piece-wise defined as p(z)=p for IzIa.The origin is depicted as O. What are the vector valued fields at.
A) point P1 at (x,y,z)=(0,a,2a).
B) point P2 at (x,y,z)=(a,0,-1/2a)
Write answers in terms of p,a and epsilon.
