(b) î - ĵ- k^
(a) î - j^ + k^
(C) -i^ -j^ - k^
(d) 3i^ + 2j^ - 5k^​

Answer 1

answer is A

I hope its help u

Answer 2

Answer:

C

Explanation:

as in the scalar product i.e dot product

the AB Sinx most be zero in perpendicular case .

in option c by taking dot product with the question the answer will be zero hence it is the solution of this question
