Preview - Modeling Electrostatics Using Netlogo

Part C: Distance

The values listed to the right of the World are recording values related to the situation set up in the World.

Find the effect on the Electrostatic Force value on the charge, q, and the Electric Field value at the position of the charge, q, if the distance, r, of q from the source charge Q, is altered. Take data by changing the position of the charge, q, in the field.

Do this by

1) clicking on Setup,

2) clicking on Go, and

3) moving your mouse around in the World to change the location of the point charge.

 

Questions

Please answer the questions below.

Record data from the values to the right of the world in the table below. Take at least 5 data points. Click on the green + in the bottom row to add more rows of data.

Do a power regression on the data to determine the dependence of Electrostatic Force and Electric Field on the distances between charges, r.
