- Q4. (a) For an infinitely long wire with uniform line-charge density, along the z-axis, find the electric field at a point (a,b,0) away from the origin. (b) A uniform line charge, infinite in extent, having charge per unit length 10 nC/m lies along the z-axis. Find the magnitude of electric field E at (6,8,3) m.A disk of radius ?=7.52 cm is centered at the origin and lies in the ?-? plane. The disk has a surface charge density σ=3.11×10^−6 C/m^2. Evaluate the electric field E(x) produced by this disk along the x-axis at point P=(1.19 cm,0.00 cm). The Coulomb force constant ?=1/(4??0)=8.99×10^9 N·m^2/C^2.Two identical thin rods of length L are each charged with a positive charge q that is uniformly distributed on each rod. The rods are arranged parallel to each other along the x direction and are separated by a distance 2d, as shown in the figure below. Determine the electric field at point P, which is located a distance d from the right endpoint of each rod. Hint: You will eventually need the following integral: น 1 S (a²+u²)3/2 du = − + C √a²+u²
