An infinite line of charge with charge density λ1 = -2 μc/cm is aligned with the y-axis as shown. 1) what is ex(p), the value of the x-component of the electric field produced by

As we know by Gauss's law that

so for line charge the gaussian surface is cylindrical in shape

so we will have

now by rearranging the terms

so here we will have to find the x component of electric field so it is given by above equation

here x = distance from the wire where we need to find electric field

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.
