Keywords: Conductors; Insulators; Electric Charge;
OBJECTIVES: Distinguish between insulators and conductors and describe how each
behaves when subjected to an electric field. Calculate, for a group of point charges at rest,
the resultant force on one of the charges caused by all of the others, or calculate the total
electric field at some point in space caused by all of the charges.
Keywords: Charges In Electric Fields; Kinematics;
OBJECTIVES: Apply the definition of electric field to solve problems involving forces on a
charged particle in an electric field, where (a) the particle is a rest under the influence of
additional forces, like gravity or tension, or (b) the particle moves in a constant electric
field. These problems may require you to calculate any of the following quantities: force,
acceleration, time, position, velocity, work, kinetic energy. For vector quantities you must
be able to calculate components, magnitudes, and directions.
