The projection vector of $\mathbf{a}$ on $\mathbf{b}$ is
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → $\left( \frac{\mathbf{a \cdot b}}{|\mathbf{b}|^2} \right) \mathbf{b}$ ##
Projection vector of $\mathbf{a}$ on $\mathbf{b}$ is given by $= \frac{\mathbf{a \cdot b}}{|\mathbf{b}|^2} \cdot \mathbf{b}$
