(& points) 1. What is the electric force between a +3 pC point charge and a -3 pC point charge if they are separated by a distance of 5.0 cm? Show your work. (pC =1.0 =105 C) Answer: (8 points) 2. The strength of an electric field at 6.0 cm from a point charge is 100.0 N/C. What is the magnitude of the source charge? Show your work. Answer: {9 points) 3. A 6.0 pC point charge is moved within an electric field and has an electric potential energy change of 18.0 J. What is the electric potential difference before and after the charge was moved? Show your work. (pC = 1.0 = 108 C)
