The picture above shows a semiinfinite solid cylinder of radius r. The cylinder has uniform distribution of charge with density ρ. Determine the x component of electrical field at point A!
(Hint: If you find a trick, it only needs a simple partial integral)

I think this is the best problems among the others. A little tricky.
can u give me hint for this problem .?
charge density * radius/pi/permittivity of free space
