Calculate the moment of force about the point `i-2hatj-hatk` of the force `3i-5hatj+hatk` acting at the point `-2hati-hatk.`

Explanation

To calculate the moment of force about a point given the force vector and the position vector, we can follow these steps:

### Step 1: Identify the vectors
We have:
- Force vector **F** = \(3\hat{i} - 5\hat{j} + \hat{k}\)
- Point of application of the force **P** = \(-2\hat{i} - \hat{k}\)
- Point about which we want to calculate the moment **O** = \(\hat{i} - 2\hat{j} - \hat{k}\)
