Question

A, B and C are three non linear, non coplanar vectors. what will u say abt the direction of A×(B×C) ?

​

Answer 1

Since B × C is perpendicular to plane of B and C, cross product of any vector will lie in the plane of B and C.

Thanks ❤️

Answer 2

Answer:

→A,→Band→C are three non-collinear, non co-planar vectors. What can you say about direction of →A×→B×→C) ? Solution : (→B×→C) will act perpecndcular to the plane constaining →Band→C and is derected as given by right hand rule.
