Please include the code used to solve the problem

Do part (b.) of problem 6 on page 87. Use documentation on the max command to figure out how to find where the maximum in E occurs, not just the maximum value of E; meaning, at what position in the E vector does its maximum value occur? Using this you can find the position z where that max E occurs. Make a simple x-y plot of electric field intensity (E) versus distance along the ring axis (z). On the plot, create a text box that gives the answer to the problem as "The maximum E of V/m occurs at cm up from the ring" inserting your answers in the blanks. Title the graph. When labeling an axis that has a variable name, symbol and units, the format is similar to that given in these two examples: Velocity, v (m/s) Potential energy, U (J) Label your axes using this format.
