Question

**Figure 2: Two resistors from the circuit, each with a voltage potential difference across them, yielding current flows $ s_1 $ and $ f_2 $.**

Diagram Explanation:
- The left section shows a resistor labeled $ r_1 $ with a resistance of 50 Ω, which is connected between voltage points $ v_1 $ and $ v_2 $. The current flowing through this resistor is denoted as $ s_1 $.
- The right section shows another resistor labeled $ r_2 $ with a resistance of 200 Ω, which is connected between voltage $ v_2 $ and the ground (earth), with the current through this resistor denoted as $ f_2 $.

**(d) Use Ohm’s law for the two resistors (Figure 2) to write two linear equations that relate $ f_2, s_1, v_1, $ and $ v_2 $ in terms of $ r_1 $ and $ r_2 $.**

(e) Rewrite your system of equations as a single matrix equation of the form

\[
B \begin{bmatrix} f \\ s \\ v \end{bmatrix} = 0.
\]

Keep in mind that $ f, s, v \in \mathbb{R}^2 $.
Give an expression for the matrix $ B $. What are the dimensions of matrix $ B $?

(f) Are the columns of $ B $ linearly independent? Justify.
