If the points with position vectors and are coplanar then
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Let A, B, C and D represents points i^-2j^+3k^, 2i^+3j^-4k^, -3i^+j^-5k^ and ai^-2j^+4k^ respectively, then AB→=i^+5j^-7k^ AC→=-4i^+3j^-8k^ AD→=a-1i^+0j^+k^ Since, A, B, C & D are coplanar, therefore…
