In this situation it is often referred to as a "'test charge " '.
3.
Stockton only allowed for a few test charges before putting it aboard " Princeton ".
4.
It is convenient to place a hypothetical test charge at a point ( where no charges are present ).
5.
It is equal to the electric force per unit charge experienced by a test charge placed at that point.
6.
It is convenient to label one of these charges, q, as a test charge, and call Q a source charge.
7.
By Coulomb's Law, this test charge will experience a force that can be used to define the electric field as follow
8.
In a magnetic field, the behavior of a test charge is determined by effects of special relativity described by the Lorentz force.
9.
An electric field is a vector field that associates to each point in space the Coulomb force experienced by a test charge.
10.
The Adventure Pass is part of the Recreation Fee Demonstration Program instituted by Congress in 1996, allowing federal land managers to test charging use fees.
