Locations A, B, C, and D are each d = 3.9e-08 m from the center of the dipole shown in the diagram below. The dipole consists of ions with charges +e and -e, separated by a distance of s = 9.8e-10 m. (Note that the diagram is not drawn to scale.) A B D C A. For the following questions, please choose the arrow from this diagram which best represents the correct answer. 1 7 6 3 9-zero magnitude 10- more information needed 1. What is the direction of the electric field at location B? 4 2. What is the direction of the electric field at location A? 8 ✓ 3. What is the direction of the electric field at location D? 4 4. What is the direction of the electric field at location C? 5. At a particular instant an electron is at location D. What is the direction of the force on the electron due to the dipole? B. An electron is at location B. What is the magnitude of the electic field at the locaiton of the electron due to the dipole? Please answer in N/C. N/C ☐

4. Consider again the situation given in Problem 1. (a) Find the center-of-mass of the system made up of m, and m,, taking the origin to be at P. (b) Draw a free body force diagram with the all of the mass (m, + m,) concentrated at this center-of-mass position. (c) Find the torque about P due to (m, + m2) concentrated at this center of mass position. How does this result compare to (d) in Problem 1? [We will make use of this technique often for certain types of future problems.]

5. A hiker travels from camp through the forest. The hiker follows 3 trails and becomes lost. The first is 180 m due west. The second one is 210 m in a direction of 35.00 east of south. The third one is 280 m at 30.0° north of east. What are A) the distance and B) direction the hiker need to walk to return to the camp?
