If A+B is a unit vector along x-axis and
Ā=i-i+k , then what is B ?
(1) j+k
(2) ĵ- k
(3) i+j+k
(4) i+j-k
Please do this in collaborated form as i am not even satisfied with its solution BrOs♥️

Answer 1

Answer:

(4) i+j-k

Explanation:

Vector A= î-j+k. Now as vectorA+vectorB is a unit vector along x-axis . (î-j+k) + vectorB=î. Therefore, vector B=j-k.

In addition to this, the two vectors yield a vector by having right displacement and perpendicular to both vectors.

It denotes clear results and includes A and B and C is the right vector values for perpendicular results.
