A uniform horizontal wire with a linear mass density of 0.520 g/m carries a 2.70 A current. It is placed in a constant magnetic field, with a strength of 4.17×10-3 T, that is horizontal and perpendicular to the wire. As the wire moves upward starting from rest, what is its acceleration? Neglect the magnetic field of the Earth.
F=ma
F=ILB
From these two equations, I derived an equation a= ILB/m. I have all the variables except L and m which will come with each other once I figure how to incorporate the mass density. So my question is, how do I use the linear mass density in this problem?
