I need help with question 18 and 19. I completed my work and not sure if it is correct. If it's not correct I need help solving please. I'm confused on these problems.

Here, we will analyze the dipole presented in Figure 6. 8.5 V/m First, construct a dipole. Click Clear All and then grab a red + 1 uC sender and then 78.9 deg 2.24 m grab a blue - 1 nC sender, placing them 2 m apart. Grab an orange Sensor and place it at point A as shown below. At this point, the center of your screen should look 1 m something like the following (except for the labels Q1, Q2, El, Ez, East, and A): AO E 2 m 8:5 V/m 78.9 deg E = (9x109 Nm2\\8.5x10-96 C 2 / ( 2 . 24 ) 2 - E = 15.25- Figure 8: Screen snapshot for Activity 3.

The steps Recall from Activity 2 that the numbers are not "exact", so that your numbers may are outlined. not exactly match those shown above. In order to find what Ene should be, follow the ) Use the parallelogram method to draw on East on the diagram below, using outline below. This is good practice for lecture. (Note: in the above image, East is the "Shapes" feature, and label it clearly. represented by the red arrow labeled "Ene".) b) Find the angle o that lies between Ez and the horizontal.

X I think my calculations could be different because I may have calculated ENEr E2 incorrectly. I referred to the Khan Academy pre-lab resources and the way it was described in the video was not exactly the same as the lab written out. I lost track after section C. The equations it had us complete was a little confusing but I think it was due to the difference of labels and keeping track of which represented what. Figure 9: Vector diagram for Q19.
