Question

Let the angle between two nonzero vectors A and B is 120 degree and resultant be C then

Answer 1

you can try formula, which is-

R^2= P^2 +Q^2 +2PQ cosQ      
where R is Resultant

You will surely get answer.

 

But if we see that  |A−B| will happen if both the vectors are in opposite direction that means angle is 180 degree.

but here in question is 120 degree hence it will surely be greater than |A-B|.

Hope it helps You out ⭐^_^⭐
Thanks ⭐(^^)⭐

Answer 2

Hey dude____
$resultant = \sqrt{ {a^{2} + {b}^{2} + ab }$
