Question

Two infinitely long conducting wires are located at x=-R and x=R, as shown below. The
wires both have linear charge density of +λ, and are parallel to the y-axis. A small
charged particle with mass m and electric charge of +q, is released from rest at a small
distance of a (a<<R), at point A.

I am interested in how the wires will be shown, infinitely long ?  Must of come off of a big spool.  What was the question anyway????

I have the exact question, radar if you are still there, or if anyone can help me with this problem. What is the net force
(magnitude and direction)
on the particle
, at point A
?

b)
What is the m
aximum
electric
potential energy of this particle? (5
pt)
c)
What is the maximum speed of this particle? (5pt)
d)
This particle will oscillate around the center at x=0. How long will it take the
particle to come back to point A? (5pt)
