The position vector for an electron is `vecr=(6.0m)hati-(4.0m)hatj+(3.0m)hatk`. (a) Find the magnitude of `vecr`.

Explanation

To find the magnitude of the position vector \(\vec{r} = (6.0 \, \text{m}) \hat{i} - (4.0 \, \text{m}) \hat{j} + (3.0 \, \text{m}) \hat{k}\), we will follow these steps:

### Step 1: Identify the components of the vector
The position vector \(\vec{r}\) has three components:
- \(x\)-component: \(6.0 \, \text{m}\) (along \(\hat{i}\))
- \(y\)-component: \(-4.0 \, \text{m}\) (along \(\hat{j}\))
- \(z\)-component: \(3.0 \, \text{m}\) (along \(\hat{k}\))
