Question

If | P×Q |= PQ sinθ = PQ then P & Q are​

Answer 1

Given :-

 | P×Q |= PQ sinθ = PQ  

To Find :-

How P & Q are wrt to each other

Solution:-

Cross product of vector = |P||Q|Sinθ

Dot product of vector = |P||Q|Cosθ

 | P×Q |= PQ sinθ = PQ  

PQ sinθ = PQ  

=> sinθ = 1

=> θ = 90°

Hence Vector P & Q are perpendicular Each other

Answer 2

If | P×Q |= PQ sinθ = PQ then P & Q are
