If the position vectors of A and B respectively `hati+3hatj-7hatk and 5 hati-2hatj+4hatk`, then find AB

Explanation

To find the vector \( \overrightarrow{AB} \) given the position vectors of points A and B, we can follow these steps:

**Step 1: Identify the position vectors of points A and B.**
- The position vector of point A is given as \( \vec{A} = \hat{i} + 3\hat{j} - 7\hat{k} \).
- The position vector of point B is given as \( \vec{B} = 5\hat{i} - 2\hat{j} + 4\hat{k} \).

**Step 2: Use the formula for the vector \( \overrightarrow{AB} \).**
- The vector \( \overrightarrow{AB} \) can be calculated using the formula:
