please just check my answers and help me out with 8a and 11. thank you!
8. Consider Figure 1 that shows an electric field extending over three regions, labeled I, II, and III and answer the following questions. 8.a. Are there any isolated charges? If so, in what region and what are their signs?? Sb. Where is the field strongest? 80 where is it weakest?) 8.d. Where is the field the most uniform? hele on 9. Choose each correct statement regarding electric field lines. a. electric field lines are closer together when the electric field is weaker 6 the electric field lines for a uniform field are parallel and equally spaced electric field lines can never cross more electric field lines will leave a 5.0 nC charge than a 2.0nC charge e. electric field lines start at negative charges and end on positive charges The direction of the electric field at any point in space is tangent to the electric field line passing through that point in space 10. Choose each correct statement regarding conductors in static equilibrium @ a conductor placed in an electric field will be polarized b. charges in a conductor are not free to move, they are locked into their position c. the electric field inside of a charged spherical conductor is zero d. the electric field outside of a charged spherical conductor is zero charges are free to move through a conductor f. the clectric filed lincs just outside of a conductor are parallcl to the surfacc excess charges will always sit on the surface of a conductor 11. Consider Figure 2, is the object shown a conductor or insulator? Explain why??7? Help Hhus ona a
Solution
8a) Yes. In region II there are Isolated negative charges.
because, electric field lines always start at positive charge and end at negative charge.
In the diagram elctric field lines are edning in region II. so, there must be isolated negative charge.
11) That must be a conductor.
Because, in electrostatic equilibrium inside a conductor electic field is zero. so, electric field lines can not penatrate through a conductor.
