Solution

Whenever the question involves finding direction we have to split the vector into its components.So here A has 2 components
A cos 120 and A sin 120
Acos120 will be along B and the other will be perpendicular.These concepts may take time for you to understand.Im sure that you will understand this more when you do many problems from this chapter
