1. Sketch the E-field lines for: a) Two positive charges and a negative charge are placed near each other. b) 3 negative charges placed near each other. 2. Two charges q₁ = 3x10 °C and q₂ = 5.0 x108 C are fixed in place 1.2m apart. a) Sketch the E-field midway between them. b) Calculate the E-field midway between them. (500 N/C away from q₂) 3. You are given an electric dipole. The distance between the charges is d. (see Lecture) a) Sketch the E-field lines b) Derive the magnitude of the E-field at a point P located a distance r (r>> d) along the perpendicular bisector of the line joining the charges. Be sure to include a sketch with the variables labeled. 4. Set up the integral to find the E-field a distance L away from an infinite line charge. The line has a total charge Q. You do not have to solve the integral. Be sure to include a sketch with the variables labeled. (see Lecture)
