Exploring Electric Fields

The following information will help guide you in the optimal use of this electric charge field simulator. To place a charge in the plane area, click on the button "place acharge" and bring the the cursor on to the plane area. Click on a point and a dialog box will appear where you can enter the exactcoordinates and the value of the charge. Note that the value is given inmultiples of a positive charge being 1.60219E-19 C. When the cursor is on the plane area, the coordinates and field angle, asseen by a test charge at that point, will appear below the plane area. To trace the field lines, click on "trace field lines" and thenbring the cursor to the point on the plane area where you would like toknow the field line configuration. This field line represents thetrajectory that a test charge... Show More
