Explain how your observations from Part 3 support theidea that the electric field in the region between the plates isuniform?
For the assignment:
Student Activity 2
Making Electric Fields Real
Introduction
You already know that noncontact forces can be explainedusing fields. How can you model an electric field?
Part 1: Laws of Electrostatics
1. What happens when objects that have like charges areplaced near each other?
They will repel away from each other as they have thesame charges for an example of positive forces are are both facingoutwards so two positive forces would push away from eachother.
2. What happens when objects that have unlike chargesare placed near each other?
They attract to each as their charges are opposite onefield is going outwards and the other one is going inwards so theyattract.
Part 2: Using Fabric to Model and Explore the ElectricField
1. Obtain a piece of four-way-stretch fabric, marbles,and chalk (or markers). You will use these materials to createmodels of the electric field near a source charge. Features of themodel are as follows:
• The fabric represents the area around a sourcecharge.
• The marble represents the small, positively chargedtest object used to determine the direction of the electric field.You will release the marble from rest at various locations on thefabric and observe its initial direction of motion, drawing arrowson the fabric to record your observations.
• The gravitational interaction is analogous to theelectrostatic interaction.
When you have finished, the arrows will show thedirection and shape of the electric field.
2. Consider how you will use your model to investigatedifferent types of charges and charge interactions. If yoursource charge is a positively charged object, how would you need toadjust (pull up or push down on) the fabric to represent this?Explain your answer.
To have a positive charge you would need to pull thefabric up as positive has charge shooting away from it. Whereas,negative has to be pulled down as negative has charges goingtowards it as the ball would be moving.
3. For each of the following five configurations, modifyyour fabric so that you are modelling the source or sources.Produce a field map for each y followinbg these steps: (1) releasea marble from rest, (2) observe its initial direction ofmotion, (3) draw a short arrow on the fabric that starts at therelease location pointing in the initial direction of motion, andthen (4) repeat for 15 to 20 locations on the fabric. Record yourresults by making sketches below or by taking a photo.
