three vectors A,B,C satisfy the relation A.B=0 & A.C=0
the vector A is parallel to
(a) B (b) C (c) B.C (d)B x C
i want the solution also
waiting for u reply
A.B = 0 , A.C = 0
if dot product is 0 then vectors are perpendicular
A.B = 0 (A perpendicular to B)
A.C = 0 (A perpendicular to C )
BxC (cross product) = vector parpendicular to B & C ...
A is perpendicular to both B,C so A is parallel to BxC hence option d is correct ...
thanks bro!!!!!!!!!!!!!!!!!!!!!!!!!!!
