Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A:
If dot product and cross product of vectors $\vec A$ and $\vec B$ are zero, it implies that one of the vectors $\vec A$ or $\vec B$ must be a null vector.
Reason R:
Null vector is a vector with zero magnitude.
Choose the correct answer:
Solution
$\vec A\times\vec B=0$ ⇒ vectors are parallel
A non-zero vector cannot be both parallel and perpendicular
⇒ one vector must be zero
✔ Assertion A is true
✔ Reason R is true
✔ R explains A
