Two infinitely long straight wires ${\mathit{A}}_1$ and ${\mathit{A}}_2$ carrying currents $\mathit{I}$ and $2\mathit{I}$ flowing in the same direction are kept ' $\mathit{d}$ ' distance apart. Where should a third straight wire ${\mathit{A}}_3$ carrying current $1.5\mathit{I}$ be placed between ${\mathit{A}}_1$ and ${\mathit{A}}_2$ so that it experiences no net force due to ${\mathit{A}}_1$ and ${\mathit{A}}_2$ ? Does the net force acting on ${\mathit{A}}_3$ depend on the current flowing through it?
