The resultant of two forces 1 and P, is perpendicular to 1 and equal to 1. What is the value of 'P' and angle between the forces?

without loss of generality, we can set it up so that the two unit vectors are along the x and y axes. So, if <b>P</b> = <x,y>

<0,1>+<x,y> = <1,0>
<x,y> = <1,0>-<0,1>
<x,y> = <1,-1>

I think you can take it from there, eh?
