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

2. 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?

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

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

5. 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
