Let and be the given lines. Then the unit vector perpendicular to both and is
(A)
(B)Correct
(C)
(D)
Answer: (B)
Solution
The direction vectors are and . A vector perpendicular to both is $×==(10-3)Missing argument for \hat\hat i-(25-4)Missing argument for \hat\hat j+(15-8)Missing argument for \hat\hat k=7Missing argument for \hat\hat i-21Missing argument for \hat\hat j+7Missing argument for \hat\hat k=7(Missing argument for \hat\hat
