Let's say you want to produce a (roughly) uniform electric fieldusing a very large nonconducting sheet. However, you still want tobe able to access the regions above and below the sheet, so a drilla small hole with a radius of 1.80 cm into the sheet. You canassume that very large means \"infinite\" in this context. The sheethas a surface charge density of 4.50 pC/m2. What is the magnitudeof the electric field at a point 2.56 cm above the sheet after thehole is drilled into the sheet? You drill the hole such that thepoint we are considering lines directly above the center axis ofthe hole.
Hint: Remember that electric fields obey the superpositionprinciple. What charge distribution can you add on top of the sheetto create the absence of charge (i.e., not net charge) in \"hole\"region?
