Question

If a parallelogram is formed with two sides represented by vectors $ \vec{a} $ and $ \vec{b} $, then $ \vec{a}+\vec{b} $ represented the, major diagonal when the angle between vectors is acute., minor diagonal when the angle between vectors is obtuse., Both of the above., None of the above.

If a → & b → represents side of parallelogram, then a → + b → is represented by diagonal of parallelogram. Case- 1 , Angle between them is acute, then the addition is represented major diagonal shown as below, Case- 2 , Angle between them is obtuse, then the addition is represented minor diagonal shown as below, a → + b → → major diagonal, if angle between vectors is acute. a → + b → → minor diagonal, if angle between vectors is obtuse.
