Question
Let $\vec{\text{A}}=3\vec{\text{i}}+4\vec{\text{j}}.$ Write four vector $\overrightarrow{\text{B}}$ such that $\overrightarrow{\text{A}}\neq\overrightarrow{\text{B}}$ but A = B.
✓

Answer

This vector A has a magnitude = 5
so take a vector $\overrightarrow{\text{B}}=5\cos\theta\hat{\text{i}}+5\sin\theta\hat{\text{j}}$
Start putting different values of $\theta$ in the above vector you can get as many vector as you want satisfying the condition $\text{A}\neq\text{B}$ but A = B.
