What is ex(p), the value of the x-component of the electric field produced by by the line of charge at point p which is located at (x, y) = (a,0), where a = 8 cm?

So our line of charge is located at the point (8cm, 0)

The Electric field of a line of charge is E (r) = λ/(ε*2*π*r) where r is the distance between our line of charge and the point where we want to calculate the electric field and λ is the linear charge density.

Here r = and here we are addressing the displacement of 8cm in the x axis.

ence, E(x,y) = λ/(ε*2*π* )

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

do you have a formula possibly
