Hand written answers with steps for questions 1,2,3

Use the following information to answer the next three questions. Three identical conducting spheres attached to insulating stands are given different charges, as shown in the diagram below. 3 & - P Conducting - = : - 8 Sphere 'i'; y ~.; y !, y Insulating Stand A B C Note: Each '+ and = represents 1 C of charge. la) Determine the initial charge of the system (total charge of spheres A, B and C). Use the following additional information to answer the next two questions. A student then performs the following procedure, in this order: Step I: Touch spheres 'A" and 'B' together, then separate them. Step 2: Touch spheres 'B' and 'C' together, then separate them. Step 3: Touch spheres 'A' and 'C' together, then separate them. 1b) Determine the charge of each individual sphere and the charge of the system (total charge of spheres A, B and C) after the student performs the procedure. Physics Principles 1c) Which of the physics principles on the back of the Alberta Education 'Physics Data Sheet' is used in the determination of the charge of the system after the student performs the procedure? ircular motion (Fe, is radially inward) Work-energy theorem Conservat mentum ion of ener Conservation of Conservation of char nucleons 0 1 2 3 4 Conser 6 7 8 Conser 9 Wave-particle duality Lab-Based Section Use the following information to answer the lab based scenario. A student performed an experiment in an attempt to verify the magnitude of charge on a single metal msatating stana sphere. The student charged a conducting sphere . 3
