Physics 012 1st Edition Lecture 4 Outline of Last Lecture I. Review Problems:II. Electric Fieldsa. E = F/q0 in N/Cb. Electric field points toward negative charges and away from positive chargesThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Outline of Current Lecture III. Electric Field StrengthIV. Electric Dipole: consists of two separated point charges that have the same magnitude but opposite signsV. Conventions for Drawing Electric Field Linesa. Field lines are oriented radially outward from positive from positive charges and inward toward negative chargesb. Field lines do not crossc. Number of field line going to/coming from a charge reflect charge magnitude (more lines = greater magnitude)d. Direction of field at any point is tangent to field line at that pointe. Field is stronger where field lines are closer
