Part I: Selecting different charge configurations Become familiar with the software simulation. Using the software arrange charge configurations involving one positive charge, one negative charge, two positive charges, two negative charges, and two charges with opposite polarity. Be sure to: Check 'Show E-field' Check 'grid' Check 'Show numbers' Vary the magnitude for these charges by dragging a charge to add or remove. Take a screen-capture of each configuration and add this to your lab report here
