Problem
The magnitude of the force experienced by a charged particle of charge q is proportional to q. So, physicists use the term *field strength* of an electric field, since this is independent of the amount of charge a particle has within the field.
How is electric field strength defined?
(1) What units does electric field strength have?
(2) How is electric field strength related to the force experienced by a charge q, in the field?
