Question

Given A vector = I hat + j hat + k hat and B vector = - I hat -j hat - k hat ( A vector- B vector) will make angle with A vector as​

Answer 1

Answer:

Avector= i+j+k

Bvector= -i-j-k

Avector-Bvector = (1-1)i+(1-1)j+(1-1)k

= 0i+0j+0k

= 0

So angle between them is 180 degrees or pi radians or 200 grades.
