The unit vector along $\hat i + \hat j$ is
$\hat k$
$\hat i + \hat j$
$\frac{{\hat i + \hat j}}{{\sqrt 2 }}$
$\frac{{\hat i + \hat j}}{2}$
If $\overrightarrow A $ is $(3,\, 4)$ unit, then show that the value of its unit vector is $1$.
Distinguish between Vector quantity and a Scalar quantity.
Explain position and displacement vectors. How the magnitude of vector quantity is represented ?
A particle is moving with speed $6\,m/s$ along the direction of $\vec A = 2\hat i + 2\hat j - \hat k,$ then its velocity is
Unit vector does not have any .......
