Find the unit vector of a vector whose co-ordinates are $(8,\, 6)$.
$0.8 \hat{i}+0.6 \hat{j}$
The expression $\left( {\frac{1}{{\sqrt 2 }}\hat i + \frac{1}{{\sqrt 2 }}\hat j} \right)$ is a
$0.4\hat i + 0.8\hat j + c\hat k$ represents a unit vector when $c$ is
Pick out the two scalar quantities in the following list :
force, angular momentum, work, current, linear momentum, electric field, average velocity, magnetic moment, relative velocity.
