Position of a particle in a rectangular-co-ordinate system is $(3, 2, 5)$. Then its position vector will be
$3\hat i + 5\hat j + 2\hat k$
$3\hat i + 2\hat j + 5\hat k$
$5\hat i + 3\hat j + 2\hat k$
None of these
The change in a vector may occur due to .....
$0.4\hat i + 0.8\hat j + c\hat k$ represents a unit vector when $c$ is
The unit vector along $\hat i + \hat j$ is
Unit vector does not have any .......
How can we represent vector quantity ?
