For the charge distributions shown on the spherical conductors below, which field lines are most reasonable?

An electric charge of +1.0x106 C is spread uniformly over one side of a styrofoam sheet by rubbing it with fur. Which of the following best represents the field lines near the sheet?

Which of the vectors best represents the electric field experienced at point P?

The negative particle in the figure below is shot from the positive plate with a low velocity. Which dotted trajectory is most reasonable?

In the figure below, a metal slab is placed in an external electric field 1. The electric field inside the metal is (a) 0 (b) (c) (d) (e) 2. The answer in (1) is true because (a) the electrons inside the metal move until they no longer experience a force, and (b) electric fields cannot penetrate a metal (c) there is zero net charge in the metal
