2. Two long, parallel wires hang by 4cm-long non-conducting cords from a common axis. The wires have a linear density A = 0.0125kg/ m and carry the same current in opposite directions. The gure below shows them in cross section with the currents owing perpendicularly to the plane of the page. .404 (a) Derive an expression for the current in each wire if the cords hang in balance at an angle a with the vertical direction (see gure)? This expression should depend only on a,/l,L0 and constants
