Question

cross product of two parallel vector is equal to square
of its magnitude this statement true or false​

Answer 1

Question :-

Cross product of two parallel vector is equal to square of its magnitude. This statement true or false ?

Answer :-

False !!

Explanation :-

Let A and B be the two vectors.

Therefore,

cross product,

A × B = |A| . |B| sin ∅

And when the two vectors are parallel, then the angle between them is zero.

That is, ∅ = 0°

Thus, sin∅ = sin 0° = 0

So, no matter whatever is the magnitude of the two parallel vectors be, the resultant will always be zero!

Hence, the statement is False .
