MCQ
Projection of vector $\vec A$ on $\vec B$ is
- A$\mathop A\limits^ \to .\mathop B\limits^ \to $
- ✓$\mathop A\limits^ \to .\hat B$
- C$\mathop B\limits^ \to .\mathop A\limits^ \to $
- D$\hat A.\hat B$
✓
Answer
Correct option: B.
$\mathop A\limits^ \to .\hat B$
b
The projection of $\vec{A}$ on $\vec{B}$ is a vector with length $P Q$ which begins at $P$ in the same direction as $\vec{B}$.
The projection of $\vec{A}$ on $\vec{B}$ is a vector with length $P Q$ which begins at $P$ in the same direction as $\vec{B}$.
The projection of $\vec{A}$ on $\vec{B}$ is defined as $\frac{\vec{A} \cdot \vec{B}}{|\vec{B}|}=\vec{A} \cdot \hat{B}$
