Answer:
False
Step-by-step explanation:
the dot product between two vectors A and B is:
A·B=AB[tex]cos\theta[/tex]
where [tex]\theta[/tex] is the angle between the vectors, if they are parallel, this angle is zero. so [tex]\theta=0[/tex]
and so the dot product is:
A·B =AB[tex]cos(0)[/tex]
and since [tex]cos (0)=1[/tex]
the dot product is equal to
A·B=AB
The dot product of parallel vectors is NOT zero
