I think... from A to B... not the direct one, but the distance perpendicular to the weight, I think...

Nope, I'm not sure. I did bad in my physics exam :S
I just remember the formula
Moment = FxD(perpendicular)
So, D should be the horizontal one (counting from the pivot to the force) in this case

BTW, the question is asking moment of the force
Moment = Fd⊥
But momentum is another thing
momentum = mv ...

moment = torque= (perpendicular distance) x (Force)

So... when heena asked 'momentum or moment of inertia??'
it should not be momentum..
