Two coaxial cylindrical conductors are shown in perspective and cross-section above. the inner cylinder has radius a = 2 cm, length l = 10 m and carries a total charge of qinner = + 8 nc (1 nc = 10-9 c). the outer cylinder has an inner radius b = 6 cm, outer radius c = 7 cm, length l = 10 m and carries a total charge of qouter = - 16 nc (1 nc = 10-9 c). what is ex, the x-component of the electric field at point p which is located at the midpoint of the length of the cylinders at a distance r = 4 cm from the origin and makes an angle of 30 degrees with the x-axis?
ex =?

The goal of this experiment was to answer the question, "how does diffraction occur? " suppose you formulated this alternate hypothesis: if the gap width is increased while keeping wavelength constant, then the observed diffraction will decrease because the less the ratio between wavelength and gap width is, the smaller the observed diffraction angle will be.to test this hypothesis, you would change the  gap widthdiffraction anglewavelength  and observe the  gap widthdiffraction anglewavelength  in the system.therefore, the independent variable would be the  gap widthdiffraction anglewavelength  and the dependent variable would be the  gap widthdiffraction anglewavelength.
