If ` -> adot -> a=0`and ` -> adot -> b=0`, then what can be concluded about the vector ` -> b`.

Explanation

To solve the problem, we start with the given information:

1. **Given**: \( \vec{a} \cdot \vec{a} = 0 \)
2. **Given**: \( \vec{a} \cdot \vec{b} = 0 \)

We need to determine what can be concluded about the vector \( \vec{b} \).

### Step 1: Analyze \( \vec{a} \cdot \vec{a} = 0 \)
