I need a step by step on how to solve. please no cursive

Problem 3 The figure to the right shows three wires either carrying current into or out of the page. The wires on the outside carry current I and the central wire a current of 21. Three Amperian paths path 3 are drawn; rank the current encircled, /1, /2, and Is for the three paths. path 2 121 O path 1 Problem 4 The cross-section of an infinite co-axial cable is shown to the right. The inner conducting wire has radius a and carries a current 2/ INTO the page distributed evenly throughout the wire. The wire shell ? O is surrounded by two thin conducting shells. Shell I carries a current I OUT OF THE page. Shell 2 carries a current of 31 shell | o OUT OF THE PAGE. (a ) Draw the magnetic field in all regions: I, II. Ill, and IV. (b)Show how the general form of Ampere's law is converted o O to a form useful in cylindrical symmetry. (c) Compute the magnetic field in all regions, I, II, Ill, and IV. Be sure to report the field as a vector and clearly state what current is enclosed (encircled) in each region. O IV
