The equation of the plane passing through three non- collinear points with position vectors a, b, c is
A. r.(b × c + c × a + a × b) = 0
B. r.(b × c + c × a + a × B. = [abc]
C. r.(a × (b + c)) = [abc]
D. r.(a + b + c) = 0
Answer:B
The equation of the plane passing through three non- collinear points with position vectors a, b, c is
A. r.(b × c + c × a + a × b) = 0 B. r.(b × c + c × a + a × B. = [abc] C. r.(a × (b + c)) = [abc] D. r.(a + b + c) = 0
