Easy Pieces in MAPLE/Mathematica/Spreadsheet
(under construction -not all items listed below are installed)
This spreadsheet allows the user to look at contour plots (both 2-D and 3-D) of the potential due to two parallel infinitely long lines of uniform charge distribution. The potential is plotted in a plane perpendicular to the charge lines. The user may specify both the charge density on the lines and the x,y coordinates of the lines.
The user may input the magnitude and coordinates of up to ten point charges and a separate test charge. The spreadsheet will calculate the force on the test charge, the field and potential at the position of the test charge, and the potential energy of the test charge. It also calculates the potential at the position of each of the ten point charges, and the potential energy of the charge configuration (minus the test charge). This spreadsheet can be used to check solutions to a wide spectrum of point charge problems typically assigned in introductory electricity and magnetism classes.
