Question
**Problem Statement:**

A long wire carrying a 5.6 A current perpendicular to the \(xy\)-plane intersects the \(x\)-axis at \(x = -1.9 \, \text{cm}\). A second, parallel wire carrying a 2.0 A current intersects the \(x\)-axis at \(x = +1.9 \, \text{cm}\).

---

**Part A:**

At what point on the \(x\)-axis is the magnetic field zero if the two currents are in the same direction?

_Express your answer to two significant figures and include the appropriate units._

\[ x = \boxed{\text{Value}} \, \boxed{\text{Units}} \]

[Submit] [Request Answer]

---

**Part B:**

At what point on the \(x\)-axis is the magnetic field zero if the two currents are in opposite directions?

_Express your answer to two significant figures and include the appropriate units._

\[ x = \boxed{\text{Value}} \, \boxed{\text{Units}} \]
