How the magnitude of vector quantity is represented ?
The magnitude of vector quantity can be represented without using arrow sign on it. It can also be represented by keeping symbol of vector quantity in modulus.
E.g. : Suppose, magnitude of force is $5 \mathrm{~N}$.
$|\mathrm{F}|=\mathrm{F}=5 \mathrm{~N}$
