Projection of vector $\vec A$ on $\vec B$ is
$\mathop A\limits^ \to .\mathop B\limits^ \to $
$\mathop A\limits^ \to .\hat B$
$\mathop B\limits^ \to .\mathop A\limits^ \to $
$\hat A.\hat B$
What will be the projection of vector $A=\hat{i}+\hat{j}+\hat{k}$ on vector $\vec{B}=\hat{i}+\hat{j}$.
If diagonals of a parallelogram are $\left( {5\hat i - 4\hat j + 3\hat k} \right)$ and $\left( {3\hat i + 2\hat j - \hat k} \right)$ then its area is
If two vectors $\vec{P}=\hat{i}+2 m \hat{j}+m \hat{k}$ and $\vec{Q}=4 \hat{i}-2 \hat{j}+ mk$ are perpendicular to each other. Then, the value of $m$ will be :
Define the scalar product and obtain the magnitude of a vector from it. Mention the direction of scalar product.
If for two vector $\overrightarrow A $ and $\overrightarrow B $, sum $(\overrightarrow A + \overrightarrow B )$ is perpendicular to the difference $(\overrightarrow A - \overrightarrow B )$. The ratio of their magnitude is
