A square insulating sheet 70.0 cm on a side is heldhorizontally. The sheet has 3.50 nC of charge spread uniformly overits area. Part A Calculate the magnitude of the electric field at apoint 0.100 mm above the center of the sheet. Express your answerwith the appropriate units. E E = nothing nothing Request AnswerPart B Estimate the magnitude of the electric field at a pointlocated a distance 200 m above the center of the sheet. Estimatethe magnitude of the electric field at a point located a distance200 above the center of the sheet. E = 2.25×10−5 N/C E = 9.83×10−5N/C E = 7.87×10−4 N/C E = 1.10×10−2 N/C Request Answer Part C Wouldthe answers to parts A and B be different if the sheet were made ofa conducting material? Select the correct answer and explanation.Would the answers to parts and be different if the sheet were madeof a conducting material? Select the correct answer andexplanation. The charge would automatically spread out evenly overboth faces, giving it half the charge density on either face as theinsulator and the same electric field only close to the sheet. Theanswer to part A would not change, but the answer to part B wouldchange. The charge would automatically spread out evenly over bothfaces, giving it half the charge density on either face as theinsulator and changing the sign of the electric field. Both answerswould change. The charge would automatically spread out evenly overboth faces, giving it half the charge density on either face as theinsulator and changing the electric field. Far away, they both looklike points with the same charge. The answer to part B would notchange, but the answer to part A would change. The charge wouldautomatically spread out evenly over both faces, giving it half thecharge density on either face as the insulator but the sameelectric field. Far away, they both look like points with the samecharge. Neither answer would change.
