Question

can two non zero vectors give zero result when the multpy each other?

​

Answer 1

Answer:

two non zero vectors and R is resultant when they multiply each other. hence, resultant becomes zero in dot product only when angle between given vectors must be 90°. here it is clear that resultant of cross product will be zero when angle between given vectors must be zero.

Answer 2

Answer:

YES

Explanation:

Depending upon the multiplication the resultant vector will change.

Dot Product: Angle between two vectors must be 90

                      a.b=abcosФ

                      if Ф=90 , cosФ=0

                      then a.b=0

Cross Product: Angle between two vectors must be 0

                          axb=absinФ

                           if Ф=0 , sinФ=0

                          then axb=0
