Hey. Was just reading through some notes, and found the equation for the strength of an electric field:
[tex]
E = \frac{F}{q}
[/tex]
Im a little confused. How can an electric field have a single value that can define its strength, if the force, F, on the test charge, q, is dependant upon the distance of the test charge from the source charge?
Thanks in advance,
Dan.
PS. This isn't a homework question, just something that i came across that had me confused.
