Write-up Criteria
1. Be neat and organized.
2. Include a drawing of the charge distribution and the point at which the E-field is
being evaluated.
3. Include a sample vector diagram, showing the electric-field vectors for critical
dq's.
4. Use the diagrams to help explain any cancellations due to symmetry.
5. Set up the integrals to determine the non-zero electric-field components. Show
your work/reasoning for constructing the integrals.
6. Solve the integrals. Box or underline your final solutions.
7. Assess: is your result reasonable? Do the solutions have the correct behavior far
away from the charge?
Problem A1:
Two circular disks spaced 0.50 mm apart form a parallel plate capacitor. Transferring 3.0
x 109 electrons from one disk to the other causes the electric field strength to be 2.0 x
105 N/C. What are the diameters of the disks?
