The figure shows three circular arcs centered at the origin of a coordinate system. On each arc, the uniformly distributed charge is given in terms of Q = 4.97 µC. The radii are given in terms of R = 11.9 cm. What are the magnitude of the net electric field in N/C or V/m at the origin due to the arcs? 2. 3R +9Q -1Q 2R +Q R (a) 1.85x106 (b) 2.23x106 (c) 2.84x106 (d) 3.12x106 (e) None of the above

The figure is a section of a conducting rod of radius R₁ = 1.20 mm and length L = 13.50 m inside a thin- walled coaxial conducting cylindrical shell of radius R₂ = 10.9R₁ and the (same) length L. The net charge on the rod is Q₁ = +3.56 × 10-¹2 C; that on the shell is Q2 = -2.05Q₁. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 2.20R2? What are (c) E and (d) the direction at r = 5.06R₁? What is the charge on the (e) interior and (f) exterior surface of the shell? R₂ Ri ex
