Two vectors vec(A)and vec(B) are at right angles to each other then

Two vectors vec(A)and vec(B) are at right angles to each other then

Two vectors vec(a) and vec(b) are perpendicular to each other if vec(a).vec(b)=0 .

Two vectors vec A and vec B are inclined to each other at an angle theta . Then a unit vector perpendicular to both vec A and vec B

The vectors vec A and vec B are such that |vec A + vec B | = |vec A - vec B| . The angle between the two vectors is

vec(A) and vec(B) are two vectors having the same magnitude but acting at right angle to each other . On the same diagram represent vec(A) + vec(B) and vec(A) - vec(B) using a suitable scale ?

For any two vectors vec a and vec b , show that : ( vec a+ vec b)dot( vec a- vec b)=0, when | vec a|=| vec b|dot
