Lesson Worksheet:Uniform Electric Fields | Nagwa

The diagrams show the electric field lines produced by
horizontal lines of negatively charged objects consisting of different numbers
of charged objects with different distances between them. The length of a
line of charge is 𝐿 and the distance
between the charges is 𝑑.

Complete the following
statements about the reasons for the shape of the resultant electric fields of
these charges:

The the distance 𝑑 between adjacent charges,
the closer the field lines near the center
of the line of charges are to being to the line. The more closely the field lines that
pass through a line of length 𝐿, parallel
to the line of charge, approximate a field, the nearer
the parallel line is to the line of charge at distances greater than from
the line of charge.
