Question

A → is a vector quantity such that A → = non-zero constant. Which of the following expression is true for A → ?, A → · A → = 0, A → × A → 0, A → × A → = 0, A → × A → > 0

MARKS App · Accepted Answer

Since both the vectors are same, they will be parallel to each other. We know that vector product of two parallel vectors is zero. Hence, A → × A → = 0 is the correct answer.
