A right circular cylinder has radius R and length L. and a nonuniform volume charge density p(p). If the z axis is chosen to coincide with the axis of the cylinder, the charge density is p(p) - p{z2) = p(z, z) = .p_0 + beta_ z. This means that the charge density varies linearly along the length of the cylinder. Find the force on a point charge q placed at the center of the cylinder. (Adapted from Reitz. Milford, and...
