Find the moment about (1,-1,-1) of the force `3hati+4hatj-5hatk` acting at (1,0,-2)

Explanation

To find the moment of the force \( \mathbf{F} = 3\hat{i} + 4\hat{j} - 5\hat{k} \) acting at the point \( (1, 0, -2) \) about the point \( (1, -1, -1) \), we can follow these steps:

### Step 1: Define the position vectors
Let \( \mathbf{A} \) be the point where the force is applied, which is \( (1, 0, -2) \). Thus, the position vector \( \mathbf{A} \) is:
\[ \mathbf{A} = 1\hat{i} + 0\hat{j} - 2\hat{k} \]
