[QUOTE="Squire1514, post: 4511159, member: 250168"] [LIST] 1. Problem Statement. [/LIST] Find the Electrostatic Field at a distance z above the xy-plane and along the z-axis due to a constant surface charge σ confined to the region a < √(x[SUP]2[/SUP]+y[SUP]2[/SUP]) < b, 0 < α < pi/2. In other words, find the Electric Field a distance z above a quarter disk occupying the region between the positive x and y axes from r = a to r = b. [LIST] [*]2. Known Equations [/LIST] E = kq/r[SUP]2[/SUP] dq = σdA dA = pi/2 * r[SUp]'[/SUp] *dr[SUP]'[/SUP] r = √(r[SUP]'2[/SUP]+z[SUP]2[/SUP]) [LIST] [*]3. Attempt [/LIST] The lack of symmetry is what loses me in this question. I know I need to set up tiny quarter rings and then integrate from A to B but I don't know what to do about the vector notation. [/QUOTE]
