well for there to be zero tension in the support wires the net force should just be the opposite of the weight just like a buoyant force on a floating object. But if I don't have a length how can i get the weight of the object. I think that's the exact thing that's screwing me up.

Magnetic force on a current carrying conductor/wire F=B(magnetic field)I(Current)L(Length)sin(theta) I have no idea where to start can you help me out here or just get me started. Whats throwing me off is this mass per unit length and the tension

A conductor suspended by two flexible wires as shown in Figure P19.18 has a mass per unit length of 0.0500 kg/m. Figure P19.18 (The picture is an attachment) What current must exist in the conductor for the tension in the supporting wires to be zero when the magnetic field is 3.70 T into...
