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

Options

  1. AA → · A → = 0
  2. BA → × A → < 0
  3. CA → × A → = 0
  4. DA → × A → > 0

Correct answer

C. A → × A → = 0

Step-by-step solution

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.
