= distance between the two wire = 5 m
= Force per unit length acting between the two wires
Force per unit length acting between the two wires is given as
N
= distance of each wire from the midpoint = 2.5 m
Magnetic field midway between the two wires is given as
There is a mirror at the bottom that reflects the light back up the tube. Also a 2nd mirror that reflects the light outside of the tube where the eyepiece is.
