The position vectors of the points A,B,C and D are 3^i−2^j−^k,2^i� – InterviewSolution

1.	The position vectors of the points A,B,C and D are 3^i−2^j−^k,2^i−3^j+2^k,5^i−^j+2^k and 4^i−^j+λ^k respectively. If the points A,B,C and D lie on a plane, the find the value of λ ?
Answer» The position vectors of the points $A, B, C$ and $D$ are $3^i - 2^j -^k, 2^i - 3^j + 2^k, 5^i -^j + 2^k$ and $4^i -^j + λ^k$ respectively. If the points $A, B, C$ and $D$ lie on a plane, the find the value of $λ$ ?
