Total charge 4. Find the total charge enclosed within each object, given the charge density function. i) A thin wire stretches along the x-axis from x = 0 meters to x = 5 meters. The charge ii) iii) density along the wire is described by the function PL = (2x + 3) nC/m. A flat, circular disk with a radius of 2 meters lies in the xy-plane centered at the origin (z = 0). The charge density on the surface is described by Ps = p² cos & nC/m², where p is the radial distance from the origin and is the azimuthal angle (0≤≤2). (Note: azimuthal angle exist in cylindrical coordinates system.) A solid sphere with a radius of 1 meter is centered at the origin. The charge density within the sphere varies with distance from the origin according to Py = = kr² C/m³, where k is a constant. Find the value of the constant k if the total charge within the sphere is 4π/3 C. 5. Given that Py = 4p2z cos nC/m³, find the total charge contained in a wedge-defined by 0
