Two vectors having equal magnitude of 5 units, have an angle of 60° b – InterviewSolution

1.

Two vectors having equal magnitude of 5 units, have an angle of 60° between them. Find the magnitude of theirresultant vector and its angle from one of the vectors.

Answer»

EXPLANATION:

$2x \cos( \frac{ \<klux>ALPHA</klux> }{2} )$

where X is the VECTOR and Alpha be the ANGLE between them

$10 \times \cos(30)$

$5 \sqrt{3}$

hope it helps
