Charge of uniform density 86 nC/m is distributed along the x-axis from x=-3 to x = +3.0 m. What is the magnitude of the electric field (in units of N/C) at the point x = +5.0 m on the x-axis?

A line of charge runs parallel to a sheet of charge, separated by a distance d = 28 cm. If the charge density of the line of charge is λ = 15 x 10-6 c/m and the charge density of the sheet of charge is o = 12 x 10-6 c/m², find the magnitude of the electric field at the midpoint between them. x 106 N/C E =

The figure is a section of a conducting rod of radius R₁ = 1.50 mm and length L = 12.10 m inside a thin-walled coaxial conducting cylindrical shell of radius R₂ = 11.8R₁ and the (same) length L. The net charge on the rod is Q₁ = +3.62 × 10-12 C; that on the shell is Q2 = -2.0501. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 2.13R₂? What are (c) E and (d) the direction at r = 5.12R₁? What is the charge on the (e) interior and (f) exterior surface of the shell? R₂ R₁
