Three vectors A, B and C are related via B+C = A. Which of the following diagrams illustrates these vectors?
According to Triangle law of Vector Addition, of two vectors are drawn such that the second vector's tail is coincident with the tip of the first vector, then the vector from the tail of the first to tip of the second vector gives the Sum of the two vectors.
Hence, in order to determine the Sum of B and C, we need to draw the tail of C at the tip of B. And then a single vector from tail of B to tip of C will give the Sum, i.e, A.
The only figure fulfilling this criteria is b.
So the correct option is (b).
