The document discusses electric forces and fields, focusing on electric field patterns created by isolated point charges. It explains the characteristics of electric field lines, including their direction relative to positive and negative charges and the concept of electric dipoles, which consist of two opposite point charges. Additionally, the document includes a quiz confirming understanding of these principles.

OBJECTIVES

3. 18.7 Electric Field Lines
An isolated point, positive charge:

4. 18.7 Electric Field Lines

5. 18.7 Electric Field Lines
Electric field lines are always directed away from positive
charges.

6. Electric field of a negative
point charge

7. Electric field of a negative
point charge
The electric field lines are directed radially inward toward a
negative point charge.

8. Electric field between two
parallel plates

9. Electric Dipole
An electric dipole consists of two separated point charges
that have the same magnitude but opposite signs.

10. Electric Dipole
An electric dipole consists of two separated point charges
that have the same magnitude but opposite signs.

11. Electric Dipole
An electric dipole consists of two separated point charges
that have the same magnitude but opposite signs.
Many molecules, such as H2O and HCl, have dipole moments.

12. Electric field between two
parallel plates

13. Electric field lines of a dipole

14. Electric field lines of a dipole
Electric field lines always begin on a positive charge and end on a
negative charge. The number of lines leaving a positive charge or
entering a negative charge is proportional to the magnitude of the
charge.

15. Electric field of two like
point charges
