By convention, the test charge is chosen to be positive. Which of the following justifies this? O The force and the electric field can be apporimxated to be the same in magnitude. This results to an easier analysis to fields and forces. O Wrong! The test charges, by convention, are chosen to be negative, since the fundamental unit of charge is taken from the charge of the electron, which is negative in terms of the polarity. O Under normal circumstances, the charges that can transfer from one object to another are protons, which have positive polarities. This results to a more grass-touching approach to electric fields as this happens in real life. O The directions of the force and of the electric field are the same. This results to an easier analysis to fields and forces.
