#1 Consider two vectors: E1 with magnitude 7 N/C and at an angle of 20 degrees above the positive xdirection, and E2 with magnitude 5 N/C and at an angle of 30 degrees to the left of the positive ydirection. (a) Visualizing vector sums: Draw a vector sum diagram illustrating the sum EN = E1 + E2 andanother of the vector difference E1 = EN − E2. Make sure to label your arrows. Please makethe diagram as close to scale as possible (use a ruler to measure, or use a program that lets youdraw accurately.) (b) Interpreting vector diagrams: From the diagram, should the magnitude of the sum be larger orsmaller than 7 N/C? From the diagram, predict the general direction of the sum, within 1/8 ofa circle (for instance, between 0 and 45 degrees above the x axis, etc.) Note, this is one goodway to check your own answers when working with vectors.
