Question

if a and b are the two vectors in a plane of different magnitude other than zero and 1, then unit vector perpendicular to both a and b is​

Answer 1

Answer:

The unit vector perpendicular to both a and b is K^(cap) because both a and b are in plane so perpendicular to them is only K cap.

Answer 2

Answer:

The unit vector perpendicular to both a and b is K cap because both a and b are in plane so perpendicular to them is only K cap.

Explanation:

From the above question,

They have given :

A and B are two vectors in a plane of different magnitudes other than zero and 1, thenunit vector perpendicular to both A and B

Let u = 1/√2. Then such a set is

(u,u,0), (0,-u,-u), and (-u,0,u).

The sum of the first and second is (u,0,-u).

The sum of the first and third is (0,u,u).

The sum of the second and third is (-u,-u,0).

The correct option is C →A×→B|→A| |→B| sinθ

The unit vector perpendicular to both a and b is K cap because both a and b are in plane so perpendicular to them is only K cap.

Let ,

   A×→B=→C

   C will be perpendicular to both →Aand →B.

   A×→B=|→A| |→B| sinθ ^c

   A×→B|→A| |→B| sinθ=^c

The correct option is C →A×→B|→A| |→B| sinθ
