Along hollow cylindrical conductor (inner radius b= 4.0 mm, outer radius c= 5.0 mm) carries a current of 24 a distributed uniformly across its cross section. a long solid wire of radius a = 2.5 mm, which is coaxial with the cylinder carries an equal current distributed uniformly across its cross-section in the opposite direction. for all the following parts, draw an amperian loop and show your steps explicitly. give direction (clockwise or counterclockwise) as viewed from the left
