If` veca = 4 hati - 3 hatj ` then find the value of `| veca |`

Explanation

To find the magnitude of the vector \(\vec{a} = 4 \hat{i} - 3 \hat{j}\), we can follow these steps:

### Step 1: Identify the components of the vector
The vector \(\vec{a}\) has two components:
- The \(i\) component (along the x-axis) is \(4\).
- The \(j\) component (along the y-axis) is \(-3\).

### Step 2: Use the formula for the magnitude of a vector
