Consider three uniform charge distributions: Spherical charge: Charge Q, Radius R, centered at the origin Line of charge: Charge Q, Length L, on the x-axis, centered at the origin • Disk of charge: Charge 2. Radius R, on the x-y plane centered at the origin. Sphere at x=y=z=0 Line on x-axis Disk at z = 0, Radius R Length Radius R Charge Q> 0 Charge Q> 0 Charge Q> 0 A) On your answer sheet, draw arrows at each dot showing the direction of the electric field due to the charge distribution at that point. The dashed line is at a 45° angle to the x-axis. Consider the directions of the fields but do not worry about the relative magnitudes. B) Check your answers to Part A (but do not change your answers) using the app: You will have click on the appropriate tabs to see the relevant information. Explain any differences between your answer and the app. For the line charge, explain what happens to the direction of the electric field for points along the 45° line, starting from close to the line and moving away, To use the app: Check the "Reverse" box to view positive charges. Change "Display: Particles to "Display: Field Vectors". Select "Finite Line" and "Charged Plate" from the drop-down indicating type of charge. Use the "Slice" tool to explore the fields. The Z-component of the electric field along the z-axis, E (), is given for each charge as: Q E (2) Z? E vi (2>R) 4 12? +R + Esphine (2) = kl Frosa (2)= 24 2x de
