Answer
given,
force per unit length = 350 µN/m
current, I = 22.5 A
y = y = 0.420 m
I₂ = 32.67 A
distance where the magnetic field is zero
there the distance at which the magnetic field is zero in the two wire is at 0.248 m.
The green bars are called "error bars." They indicate the range of uncertainty that scientists have about the data on the graph.
(Note: Not all error bars are shown.)
Why do you think these error bars are smaller near the year 2000 than in the 1890s?

The De Broglie wavelength of the electron is
And we can use De Broglie's relationship to find its momentum:
Given
, with m being the electron mass and v its velocity, we can find the electron's velocity:
This velocity is quite small compared to the speed of light, so the electron is non-relativistic and we can find its kinetic energy by using the non-relativistic formula:
