Question
A solid, infinite metal cylinder of radius a = 1.5 cm is centered on the origin, and has charge density ?inner = -5 nC/cm. Surrounding this cylinder is a cylindrical metal shell of inner radius b = 3.0 cm and outer radius c = 4.5 cm. This shell
is also centered on the origin, and has total charge density ?shell = +2 nC/cm.
1. If a positive point charge were placed on the x-axis at the location x = 2 cm and released from rest, it would
a. move away from the origin.
b. move toward the origin.
c. remain at rest.
2. If a positive point charge were placed on the x-axis at the location x = 6 cm and released from rest, it would
a. move away from the origin.
b. move toward the origin.
c. remain at rest.
3. . If a positive point charge were placed on the x-axis at the location x = 3.75 cm (halfway between the inner and outer surfaces of the shell), it would
a. move away from the origin.
b. move toward the origin.
c. remain at rest.
