Solution:
Given that, A.B = 0 and A . C = 0
So, A is perpendicular to B as well as C.
Let D = B x C i.e., direction of D is perpendicular to the plane containing B and C.
Therefore, A is parallel to D i.e., A is parallel to B x C.
Three vectors satisfy the relation A . B = 0 and A . C = 0, then A is parallel to
Three vectors satisfy the relation A . B = 0 and A . C = 0, then A is parallel to
