< physic qn > please help me with this question please , I’ve gotten the wrong answer but I still don’t understand why must we use 0.4m as the distance for force F.

That’s because force is relative to the distance from the pivot
The centre pivot to be exact
F = 10 N is correct. The perpendicular distance from the line of action (or direction) of force F, to the labelled pivot is 0.50 m. Not 0.40 m.
