Question

Transcribed Image Text:A team of storm physicists is attempting to replicate lightning
by charging two long cables stretched over a canyon, as
shown. One cable will attain a highly positive and uniform
charge density of +A, and the other will attain the same
amount of charge density but opposite in sign (i.e., -A). Since
the appearance of lightning directly depends on the electric
field strength created by charge separation, they must derive
an expression for electric field strength between the
two cables.
The cables are sufficiently long to be approximated as
infinitely long. Calculate the magnitude of the electric field
strength E between the two cables as a function of A (the
linear charge density) and r (the distance from the positively
charged cable). Use co as the permittivity of free space, and
assume the wires are separated by a distance D.
E =
If the value of the linear charge density is A = 50.5 µC/m and
the distance between the two cables is D = 40.5 m, calculate
%3D
the electric field midway between the two cables.
