General Physics> vectors...

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 ...

Approved

hello students

Three vectors satisfy the relation A.B=0andA.C=0then A isparallelto. A isperpendicularto bothBandCand BxxC is alsoperpendicularto bothBandC. Therefore, A isparallelto BxC.

Hope it helps
Thankyou

Dear Student

Given, A⋅B = 0, ∴ A is ⊥ to B
also, A⋅C = 0, ∴ A is ⊥ to C
As B×C is ⊥ to both B and C,
so B×C is parallel to A.

I hope this answer will help you.
Thanks & Regards
