    Ooh that's a tough one!

    Well since it says that it just causes it to tip, you can basically assume the moments clockwise/anticlockwise about a point on P are equal.

    Now since it's tipped anticlockwise, where exactly does our "pivot" lie in terms of a position on the P support? Which point of P is the pivot? Once you've determined this, use the length measurements you've been given to take moments about the pivot point of P - they should be equal remember either direction since it has just tipped!
