Question

can two vectors of same magnitude have resultant equal to either of them explain

Answer 1

Answer:

Yes

Explanation:

let two vectors A and B and angle between then is x

let magnitude of resultant is a

$a = \sqrt{ {a}^{2} + {b}^{2} + 2ab.cosx }$

squaring and solving we get

b(b+2a cos x)=0

b=0 , so if other vector is zero vector

or

$cosx = \frac{ - b}{2a}$
