Question

A vector= i+j+k and B vector =xi+j-2k. if A vector and B vector are perpendicular find x

Answer 1

the ans is x=1

branliest branliest branliest

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.
