Question

Transcribed Image Text:**Description:**
The image shows a horizontal, long current-carrying wire hanging from a vertical thread. The diagram indicates that the current is oriented into the plane, as denoted by the symbol "⊗" (a circle with an X inside). A tension \( T \) is acting on the string.
**Wire Specifications:**
- Current \( I = 0.3 \) A
- Length \( L = 80 \) cm
- Mass \( m = 50 \) g
**Magnetic Field:**
A uniform magnetic field \( B = 0.4 \) T is applied along the negative x-axis.
**Coordinate System:**
The image includes an x-y coordinate system indicating the directions of the axes.
**Question:**
What is the value of the tension in the string?
**Answer Choices:**
- 0.2 N
- None of the other answers
- 0.4 N
