Question

Now, the differential amount of charqe dQ on dx will setup a tiny electric field dE at point P. Sketch this field at P before going any further. Now, since there is symmetry in the problem (do you agree with this?) then it should be possible to find an identical dQ, the same distance from the y-axis as the original dQ that you had chosen, but on the other side of the rod. This will also set up a tiny electric field dE at P. Sketch this field also at P. Which of the following would be true? Note that there are more than one correct answers. Give them all. Give your answer in the form "M", "N". Note that a comma followed by a space is used to separate the letters. A. The y components of the two dE's will cancel out leaving only the x components. B. The x components of the two dE's will cancel out leaving only the y components. component that do o ane out o give 2ro wi components that do not cancel out to give zero will be identical. D. Because of the symmetry the components that do not cancel out to give zero will be not be identical.
