Question

If , then what can be concluded about the vector ?

Answer 1

The given vectors are a → and b → with condition,

a → ⋅ a → =0(1)

a → ⋅ b → =0(2)

From condition (1),

a → ⋅ a → =0 | a → | 2 =0 | a → |=0

Therefore, a → is zero vector, then b → satisfies the condition (2) for any vector.

Hence, b → is any vector.
