Question

write the unit vector perpendicular to i^+j^and j^+k^

Answer 1

i^+j^ perpendicular is k^ j^+k^ perpendicular is i^

Answer 2

Answer:

Given vector is i+j+k

Let another vector be xi + yj + zk

Since they are perpendicular, there dot product is 0

Therefore, x + y + z =0

Now you can put value of x , y ,z of your choice.
