Question

If vectors a 1 → = x i ^ - j ^ + k ^ and a 2 → = i ^ + y j ^ + z k ^ are collinear, then a possible unit vector parallel to the vector x i ^ + y j ^ + z k ^ is:, 1 2 - j ^ + k ^, 1 3 i ^ + j ^ - k ^, 1 2 i ^ - j ^, 1 3 i ^ - j ^ + k ^

MARKS App · Accepted Answer

a → 1 and a → 2 are collinear So, x 1 = - 1 y = 1 z Unit vector in direction of x i ^ + y j ^ + z k ^ = ± 1 3 i ^ - j ^ + k ^
