A circular disk has a charge density 0f G C/m^2 and a radius of R m.

A test charge, P, is located Z m above the center of the disk on a line perpendicular to the disk and passing through the center of the disk.

Using polar coordinates (d(area) = r*dr*d(theta)) find the value of the electric field ,E, at P.

Electric field above surfaces

Electric field above surfaces. See attached file for full problem description.
1. find the electric field a distance z above one end of a straight line segment of length L, which carries a uniform line charge lamda.
check that you formula is constistent with what you would expect for the case z >>L.

2. Find the electric field a distance z above the center of a flat circular disk of radius R, which carreis a uniform surface charge.
What does your formula give in the limit R --> infinity? Also check the ase z >>R.
