If the vectors \( -3 i+4 j+\lambda k \) and \( \mu i+8 j+6 k \) are collinear vectors, then find \( \lambda \) and \( \mu \). |

Answer» Given that ⇒ the vectors -3i + 4j + λk and μi + 8j + 6k are collinear vectors. Collinear means the vectors lying on the Same Line. So the vectors can be
In both cases, the ratio of their respective components will be Equal. So we have -3i + 4j + λk & μi + 8j + 6k Comparing both, we get -3/μ = 4/8 = λ/6 -3/μ = 1/2 = λ/6 ⇒ -3/μ = 1/2 And 1/2 = λ/6 ⇒ μ/-3 = 2/1 And λ/6 = 1/2 ⇒ μ = -3(2) And λ = 6(1/2) ⇒ μ = - 6 And λ = 3 |
