Physics 012 1st Edition Lecture 2Outline of Last Lecture I. Fundamental Charge (e)a. e = 1.6 x 10^-19 Cb. electron charge = -ec. proton charge = +eII. Total Charge (q)a. q = Nei. N = number of particles (integer)III. Charge Transfer: 3 typesa. By frictionb. By conduction (contact = direct flow of electrons)- uncharged object ends up with same charge as charged objectc. By inductions (no contact, just polarization)- uncharged object ends up with opposite charge of charged objectOutline of Current Lecture II. Insulators: contain no free electrons that can move around easilya. Conduct electric charge poorlyIII. Coulomb’s Law: the magnitude F of te electrostatic force exerted by one point charge q1 on another point charge q2 is directly proportional to the magnitudes |q1| and |q2| of These 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.the charges and inversely proportional to the square of the distance r between them (Cutnell 535)a. F = (k |q1||q2|)/r2b. k = proportionality constant = 8.99 x 109 (N*m2)/C2F12 = - F21 (Newton’s 3rd Law)Σ F = ma, same mass = same a, just in different Directions (Newton’s 2nd Law)Problem: Where can a 3rd charge (q0) be placed so Fnet on it is
