Question 1
Two forces P and Q act on an object inclined to one another. In which direction does the object move?
The right answer is the one marked above.
In a direction lying between the directions of P and Q. With two inclined forces applied, the object moves neither the way P points nor the way Q points.
Neither one "wins" — the object goes to a compromise between them. There is no reason for it to go the opposite way; both forces push it forward.
