Question

Three vectors relations is true? M, N and S are shown in the vector diagram. Which of the following A) S м м- N B) S %3D C) S = N- M %3D -(M + N) D) S

Answer 1

By the triangle law of vector addition if two sides of a triangle represents two vectors, then the third side closing in the opposite direction will represent the resultant of the other two vectors.

Applying the triangle law for this above diagram we have

$\overrightarrow{N}+\overrightarrow{S}=\overrightarrow{M}$

$or,\ \boxed{ \overrightarrow{S}=\overrightarrow{M}-\overrightarrow{N}}$

Option B is correct.
