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. &+ * o Conducting - T e . Sphere '.. y '-'; y ~., y Insulating Stand - - s = 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 1. 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. 1) 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 5- CORIBYMIon Of cormsntem, & Conservation of 0 (Fpgy is radially inward) theorem procedure? & Conservation of 1 7 Conservation of char 8 Conservation of nucleons % 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 imsutating stand sphere. The student charged a conducting sphere % s . S megatively charged metal sphere connected to an insulating stand by putting it in T contact with a Van der Graaf generator. The student then contacted the charged, conducting sphere with an 1 identical conducting sphere and then separated them. l . e g i i The student then put one of the conducting sphere apparatuses on a digital scale and zeroed it so that the scale had a reading of 0.00 g. The student then put the other conducting sphere at different distances from the conducting sphere on the scale and measured the mass imsulating stand reading for each trial. The graph of the student's initial results is shown below: e muvs.1/ 50 m(x10~*kg) 25 Ay 150l ) ) 100 7 () 2a) Determine the slope of the m vs .,Lz graph, in the correct units. Note: Do not round your slope. 2b) Graphically (using your slope), determine the charge on one of the charged metal spheres. Use the following information to answer the next question. Identical spheres A, B, and C, each with a charge of magnitude 6.0 x 10- C, are situated at three corners of a square whose sides are 0.25 m long. Spheres 'A' and 'C' are positive, while sphere 'B' is negative. Point '' is located at the other corner of the square, as shown in the diagram below. A B 0.25 m x 3) Determine the net electric field at point 'x". Include a vector addition diagram of the net eletric field at point x" as part of your solution
