Find the moment of ` vec F` about point (2, -1, 3), where force ` vec F=3 hat i+2 hat j-4 hat k` is acting on point (1, -1, 2).

Explanation

To find the moment of the force vector \(\vec{F}\) about the point \(A(2, -1, 3)\), where the force \(\vec{F} = 3\hat{i} + 2\hat{j} - 4\hat{k}\) is acting on the point \(B(1, -1, 2)\), we will follow these steps:

### Step 1: Define the Points
Let:
- Point \(A\) be \(A(2, -1, 3)\)
- Point \(B\) be \(B(1, -1, 2)\)

### Step 2: Find the Position Vector \(\vec{AB}\)
