Vector Quantities Assignment | Professional Writing Services
Examine the diagram shown. It shows a finite disk of radius a, and two particles A and B. Each object is electrically charged. – Particle B is on the central axis of the disk. – Particle A is directly above the edge of the disk. – Both particles are the same distance d above the plane of the disk. – The total charge on the disk is spread evenly across its upper surface. dl The values for the parameters are given below: a = 2.5 cm d = 6.0 cm 9A = -25 nC qB = +16 nC Qtotal, disk = +60 nC.
Your ultimate goal is to calculate the electrical force vector acting on particle B and its magnitude. Follow these steps on your way to the goal – I will be marking the steps as well as the calculations. Draw coordinate axes on a sketch of the arrangement. Now I will know your definition of the x, y and z directions. Explain your strategy for finding the solution in words, so I know what you are attempting to do. Draw vectors for electric fields and forces relevant to the problem on your sketch. This establishes your qualitative thinking regarding the problem. Now do any necessary calculations. Break them into steps, and give them headings so that I know what a particular calculation is trying to achieve. Carry units through all calculations! Vector quantities should be managed in the calculations with correct vector notation (i.e., with the i, j, k unit vectors), or at the very least with very clear indications of the directions that various vector components will point in. Your final answer will be the electrical force acting on particle B. Please give it a. in component form (with the i, j, k unit vectors), and b. give its magnitude and the angle it makes with your coordinate axis (be clear regarding which angle you are giving me!). When you have obtained your answers, be sure that you have the clearly indicated on your work. Now write a short assessment: are the values of quantities and their directions (if appropriate) sensible? Why do you think so?
