## Homework Statement

The resultant R of vectors P and Q is perpendicular to P and R=P both, then the angle between P and Q is what?

Now, what is the concept behind it? Could you provide me with an image of the resultant perpendicular to two vectors so that I can understand the concept and start solving the problem?
