Q: If the electric field due to a charged infinite plane sheet is E, what is the electric field at a point on either side of the sheet?

Solution: The electric field due to an infinite plane sheet is constant and equal to E on both sides, thus the total field is 2E.

Steps: 5

Step 1: Understand that an infinite plane sheet has a uniform charge distribution.
Step 2: Know that the electric field (E) created by this charged sheet is constant and does not depend on the distance from the sheet.
Step 3: Recognize that the electric field points away from the sheet on both sides if the sheet is positively charged (or towards the sheet if negatively charged).
Step 4: Since the electric field is the same on both sides of the sheet, it is E on one side and E on the other side.
Step 5: To find the total electric field at a point on either side of the sheet, you add the electric fields from both sides: E + E = 2E.
