A) \[{{120}^{o}}\]
B) \[{{110}^{o}}\]
C) \[{{60}^{o}}\]
D) \[{{150}^{o}}\]
Correct Answer: A
Solution :
Key Idea: Two vectors (inclined at any angle) and their sum vector form a triangle. It is given that two vectors have a resultant equal to either of them, hence these three vectors form an equilateral triangle each angle of \[{{60}^{o}}\]. In the figure \[\vec{A}\] and \[\vec{B}\] are two vectors \[(\vec{A}=\vec{B})\] having their sum vectors \[\vec{R}\] such that.You need to login to perform this action.
