`vecA=(3hati+2hatj-6hatk)` and `vecB=(hati-2hatj+hatk)`, find the scalar product `vecA` and `vecB`

Explanation

To find the scalar product (dot product) of the vectors \(\vec{A} = 3\hat{i} + 2\hat{j} - 6\hat{k}\) and \(\vec{B} = \hat{i} - 2\hat{j} + \hat{k}\), we will follow these steps:

### Step 1: Write down the vectors
We have:
\[ \vec{A} = 3\hat{i} + 2\hat{j} - 6\hat{k} \]
\[
