Physics · Secondary 4 · Medium · Centre of gravity and stability
An irregular metal plate is hung from point A and allowed to come to rest. A plumb-line is used to draw a vertical line down the plate from A. The plate is then hung from point B and another vertical line is drawn. Where is the centre of gravity of the plate?
- At the midpoint of the line drawn from A
- At the midpoint of the line drawn from B
- At the lowest point of the plate when it hangs from A
- At the point where the two drawn lines intersect
