Preview - Modeling Electrostatics Using Netlogo

Part C: Target Shoot with a Charge stream.

When you hit setup the following characteristics update:

     1.  E-field Lines

     2.  Parallel Plate colors

When you hit setup and go the following characteristics update:

     1.  E-field Value and E-field vector

     2.  Force Value and Force vector

     3.  Charge in the field value and color of charge

     4.  Mass of the charge in the field and size of the charge

The positive plate and positive charge in the model will be Red. The negative plate and negative charge in the model will be Blue.

In the current setup the force on the point charge is either right or left depending on electric field direction and charge. We want to introduce a stream of charges moving upward with initial velocity, chargeVelY, from the bottom center between the plates. Turn on the ChargeStream switch followed by setup and go. Change variable values to get a path that is not straight up the screen.

Questions

Please answer the questions below.

Describe the shape of the path the charges take as they move from the bottom to the top of the screen if there is a y-velocity and a force in the perpendicular x-direction only.

What part of physics that we studied in semester 1 does this remind you of? Be fairly specific.

In the table below set up values for mass, chargeCoefficient, chargeExponent, chargeVelY, and strength that will allow your stream to hit the numbered targets at the top.
