Question
In the figure, two semicircular arcs have radii \( R_2 = 16.7 \, \text{cm} \) and \( R_1 = 7.30 \, \text{cm} \), carry current \( i = 0.803 \, \text{A} \), and have the same center of curvature \( C \). What are the (a) magnitude and (b) direction (into or out of the page) of the net magnetic field at \( C \)?

**Diagram Explanation:**
- The diagram is a semicircular setup with two arcs, both sharing the center of curvature \( C \).
- The outer arc has a radius \( R_2 \) and the inner arc has a radius \( R_1 \).
- The arcs carry the same electrical current \( i \).

**Questions:**
(a) Calculate and enter the magnitude of the net magnetic field (unit options provided are \(\mu\text{T}\)).

(b) Determine and select the direction of the net magnetic field: into or out of the page (options available in a dropdown).

**Answer Fields:**
- For (a), a text box is provided for numeric input, and a dropdown menu specifies units.
- For (b), a dropdown menu allows selection between "into" or "out" of the page.
