Position of a particle in a rectangular-co-ordinate system is $(3, 2, 5)$. Then its position vector will be
If $\overrightarrow A $ is $(3,\, 4)$ unit, then show that the value of its unit vector is $1$.
When it is needed to use vector ?
The angle between vectors $\vec a$ and $\vec b$ is $\frac{\pi }{6}$. The angle between vectors $ - 3\vec a$ and $ 2\vec b$ is
The change in a vector may occur due to .....
