Find the scalar components and magnitude of the vector joining the points `P(x_1,y_1,z_1)`and `Q(x_2,y_2,z_2)`

Explanation

To find the scalar components and magnitude of the vector joining the points \( P(x_1, y_1, z_1) \) and \( Q(x_2, y_2, z_2) \), we can follow these steps:

### Step 1: Write the Position Vectors
The position vector of point \( P \) is given by:
\[ \vec{P} = x_1 \hat{i} + y_1 \hat{j} + z_1 \hat{k} \]
The position vector of point \( Q \) is given by:
