And here is the 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.
a) What is the net force (magnitude and direction) on the particle , at point A ? (Ignore gravity)
b) What is the maximum electric potential energy of this particle?
c)What is the maximum speed of this particle?
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)
(Hint:You need to use what you have learned about simple harmonic motion in PHY2048 and use the approximation of€R2−a2≈R2)
(This hint is only for part d, and should not be used for part a,b,c)

Answer 2

(R^(2)-A^(2)≈R^(2))*fixed typo
