137. Figure 35 shows, in cross section, two wires that are parallel, straight, and very long. The first wire, located at \( (0,5.0) \mathrm{cm} \), carries a current of \( 6.0 \) A into the page, and the other wire, located at \( (-3.0,4.0) \mathrm{cm} \), carries a current of \( 7.5 \) A out of the page. What magnetic field do these two wires produce at the origin \( \mathrm{O} \) ? \( ( \) Ans: \( 18 \hat{\mathbf{j}} \mu \mathrm{T}) \) Figure 35
