Group Question - Predict the net electric force a test charge will experience when placed next to a charge dipole. Draw three vectors for each point - one for each charge and one for the net force. In the next diagram sketch your prediction for the electric field around the dipole. + + O Class Question - Draw the electric field around a dipole. Do the field lines ever cross? Explain why. + What is the charge dipole a basic model of? Challenge: What will the electric field between two oppositely charged parallel plates look like? Use the ideas from the line of charge and the dipole help with this! If in doubt, think about the forces acting on a test charge!
