The combined effect is the sum of the individual effects. •  So, when many charged particles are present, their electric fields (E=F/q) add like vectors January 22, 2014 Physics 104, Spring 2014 25 Electric Field Patterns •  An electric dipole consists of two equal and opposite charges •  The density of lines between the charges indicates the strong electric field in this region January 22, 2014 Physics 104, Spring 2014 26 Electric Field Patterns Unequal and unlike charges •  Note that two lines leave the +2q charge for each line that terminates on -q January 22, 2014 Physics 104, Spring 2014 27 Electric Field Patterns Two equal but like point charges •  At a great distance from the charges, the field would be approximately that of a single charge of 2q •  The bulging out of the field lines between the charges indicates the repulsion between the charges •  The low density of field lines between the charges indicates a weak field in this region January 22, 2014 Physics 104, Spring 2014 28 Charges in a condu...
