4. Four point charges are placed as shown below. Find the net field at the test point P, located a distance y above the middle of the sources, for each of the following sets of parameters. The distance d between adjacent sources is d=1.0 x 10-4 m. You may and even are encouraged to reuse any calculations that are needed more than once, symmetry arguments, and appropriate approximations as long as you make it clear what you are doing. Your calculations need to give numbers that would be good to 2 significant figures.
