[/B]1. Homework Statement
The figure is a cross section through three long wires with linear mass density 43.0. They each carry equal currents in the directions shown. The lower two wires are 4.0 cm apart and are attached to a table.
2. Homework Equations
What current will allow the upper wire to "float" so as to form an equilateral triangle with the lower wires?
3. The Attempt at a Solution
I am not sure where to start could someone give me a hint at what to do?
