Question

Find the magnitude and direction of the resultant of two vectors

Answer 1

Hey there!

♦ Formula to find magnitude of the resultant of two vectors:

$\boxed{R = \sqrt{|A|^2 + |B|^2 + 2AB \ cos\theta}}$

♦ Formula to find direction of resultant of two vectors:

$\displaystyle \boxed{\alpha = tan^{-1} \dfrac{B \ \sin\theta}{A + B\cos\theta} }$
