SSM WWW Figure 23-42 is a section of a conducting rod of radius R 1 = 1.30 mm and length L = 11.00 m inside a thin-walled coaxial conducting cylindrical shell of radius R 2 = 10.0 R 1 and the (same) length L . The net charge on the rod is Q 1 = +3.40 × 10 −12 C; that on the shell is Q 2 = −2.00 Q 1 . What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 2.00 R 2 ? What are (c) E and (d) the direction at r = 5.00 R 1 ? What is the charge on the (e) interior and (f) exterior surface of the shell? Figure 23-42 Problem 29.

Paraxial design of a field flattener. Imagine your optical system has Petzal curvature of the field with radius
p. In Module 1 of Course 1, a homework problem asked you to derive the paraxial focus shift along the axis
when a slab of glass was inserted in a converging cone of rays. Find or re-derive that result, then use it to
calculate the paraxial radius of curvature of a field flattener of refractive index n that will correct the observed
Petzval. Assume that the side of the flattener facing the image plane is plano. What is the required radius of
the plano-convex field flattener? (p written as rho )
