Question

11. Two vectors having magnitudes A and root3 A are perpendicular to each other. What is the angle between their
resultant and Ā?​

Answer 1

Answer:

$\tan( \alpha ) = \sqrt{3} a \sin(90 ) \div a + \sqrt{3} a \cos(90)$

cos90°=0

sin90°=1

therefore

tan(alpha) =√3A/A

tan(alpha) =√3

alpha=60°
