Find a vector in the direction of vector `2 hat i-3 hat j+6 hat k` which has magnitude `21` units.

Explanation

To find a vector in the direction of the vector \( \mathbf{A} = 2\hat{i} - 3\hat{j} + 6\hat{k} \) that has a magnitude of 21 units, we can follow these steps:

### Step 1: Identify the given vector
The given vector is:
\[ \mathbf{A} = 2\hat{i} - 3\hat{j} + 6\hat{k} \]
