Question

Find V, and V2 in the circuit in Fig. P3.6 using nodal analysis.

**Nodal Analysis: Finding \( V_1 \) and \( V_2 \) in a Circuit**

**Problem Statement:**
3.6 Find \( V_1 \) and \( V_2 \) in the circuit in Fig. P3.6 using nodal analysis.

**Figure P3.6 Description:**
The circuit diagram in Figure P3.6 consists of multiple components:
- A current source of 4 mA (milliamperes) is connected to a node.
- At this node, a 6 kΩ (kilohms) resistor is connected to the ground, with the voltage at this node denoted as \( V_1 \).
- Moving towards the right, there is a 4 kΩ resistor connected in series between two nodes.
- The second node, where the voltage is denoted as \( V_2 \), has a 3 kΩ resistor connected in parallel to a current source of 6 mA.
- Additionally, there is a 6 kΩ resistor connected to another node at the extreme right from \( V_2 \), going to the ground.

**Diagram Description:**
1. **Left Node:** Connected to the 4 mA current source and a 6 kΩ resistor to the ground, marked as \( V_1 \).
2. **Middle Node (between Resistors):** Connected via a 4 kΩ resistor from the left node, and has a parallel connection with the 6 mA current source and a 3 kΩ resistor, and another connection to \( V_2 \).
3. **Right Node:** Connected to the 6 kΩ resistor grounded, marked as \( V_2 \).

The goal of the problem is to use nodal analysis to determine the voltages \( V_1 \) and \( V_2 \) at these nodes.

**Steps for Nodal Analysis:**
1. **Identify all Nodes and Assign Variables:**
   - \( V_1 \) at the leftmost node.
   - \( V_2 \) at the middle node between \( 4 \text{ kΩ} \) and \( 3 \text{ kΩ} \) resistors.

2. **Apply KCL (Kirchhoff's Current Law) at each node:**
   - For \( V_1 \): Sum of currents leaving \( V_1 \) = Sum of currents entering \( V_
