PHYSICS 5C Chapter Notes - Chapter 21: Surface Charge, Probability Distribution, Algebraic Number Field
Document Summary
V j for single charges multiple charges electric field lines must point away from positive charges and point toward negative charges the electric field strength is proportional to the density of the field lines. At locations very close to a positive charge , there is a high density of field lines pointing away from the positive charge . A positive test charge placed here would strongly repel. Electric dipole : electric field of two equal but. Oppositely signed charges the field is stronger in the region between the two charges because the fields from each individual charge are in the same direction and so their strengths add . Field lines must begin on positive charges and terminate on negative charges. Isolated charges where field lines will originate or terminate at infinity. The number of field lines leaving a positive charge or entering a negative charge is proportional to the magnitude of the charge.
