Question

Two charged concentric spherical charged surfaces lie at the center of a Gaussian surface in the shape of a
dodecahedron. The inner sphere has charge +20 mC and radius 10 cm. The outer sphere has a charge -43 mC and
radius 30 cm. The dodecahedron surface may be inscribed within a sphere of radius 100 cm. a. Draw a physics
diagram of the problem. For the dodecahedron, you may just draw the sphere that inscribes it. b. Compute the electric
flux through one face of the dodecahedron.

Imagine that you are given a box which is said to be filled with various charged objects. You cannot open the box but are tasked with determining what could possibly be inside of it. Q2: If you can measure the electric field at a point in space then you can estimate the symmetry of the charge distribution inside of the box. For spherical, cylindrical, and planar symmetry provide a diagram of the expected electric field lines around the box for each situation. Using fundamentals of static electric fields explain the shapes of the field lines in each situation. Indicate quantitatively how the magnitude of the field changes as you move away from the box Q3: Since the box has finite size, describe how the field lines in each case outlined in question 2 would differ from their idealized charge distribution. For all three situations, what would the charge distribution look like when you move far away from the box?

Electric Fields 1. A wire has been given a net positive electric charge Q evenly distributed along its length. The wire has a length of L and is located on the x-axis with its left end at the origin as drawn. Set up the integral you need to do to find the electric field at a distance d to the left of the origin. Some steps you may wish to follow are: a. Figure out the direction the electric field will have at our location x = -d. This will be the same as f b. Write the differential charge dą in terms of the charge per length and a differential length. c. ris a function of x which means we have to integrate to find the electric field. Write down r. d.
