For each drawing, select which of the above rules are broken or if the diagram is essentially correct. http://imgur.com/a/Hg23p 2. Relevant equations Rule 1: direction from + to − Rule 2: number proportional to charge Rule 3: radial symmetry close to charge Rule 4: spacing inversely proportional to field magnitude Rule 5: field tangent to any line 3. The attempt at a solution For the 1st question: Rule 1 is not violated, Rule 2 is violated since the charge is different, Rule 3 is not violated since there is symmetry, Rule 4 is not violated, Rule 5 is not violated For the 2nd question: Rule 1 is not violated since it is going to the negative charge, Rule 2 I'm not sure, Rule 3 is violated since there is no symmetry, Rule 4 I don't know, Rule 5 is violated the electric field is not tangent to the field line Thanks!
