Complete the following assignment using the interactive PhET simulation: PhET Simulation on Charges and Fields and other resources you may find on the internet. Electric Field Simulations 1. Draw the electric fields for the following: . Single positive charge . Single negative charge . Two equal positive charges placed a distance apart . Two equal negative charges placed a distance apart . Equal unlike charges (place additional charges one on top of the other) placed a distance apart . Unequal like charges placed a distance apart . Unequal unlike charges placed a distance apart 2. In a simulation that shows you electric field lines and allows you to alter the charge, what do you notice about the relationship between charge and electric field lines? 3. Do field lines ever cross? Why? 4. What can be said about the electric field between two oppositely charged parallel plates? 5. Does the separation of the plates affect field intensity? How?
