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

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.
