Question

(ii) If 'theta’is angle between A and B then what will be the component of Ā along B?
​

Answer 1

If ∅ is the angle between A and B the the component of A along B will be A cos∅.

• The component of A that is perpendicular along B will be A sinФ.
• The component of A would begin at the same point from where the B vector starts.
• The direction of the vector can be in the opposite direction or the same direction as that of B, but the magnitude of the component would be A cos∅ along B and the one perpendicular to it would be A sin∅.
