Question

what is resultant vector of a bar and b bar​

Answer 1

$|barR| = |barA| + |barB|$

HeY mate !! Listen..

Here bar r is the Resultant of the vector A and B

Answer 2

$r = \sqrt{ {a}^{2} + {b}^{2} + 2ab \: \cos( \alpha ) }$

where r = resultant

$\alpha = angle \: between \: a \: and \: b$
