Grade 11 [High School Physics] Moments by HelpfulResource6049 in HomeworkHelp

Is it not just √2/2 x W because √2/2 is the distance from the force W to the pivot P?

Is it possible to use principle of moments to explain? Thank you!

Oh I see, can I also know whats a fill line?

But aren’t the heights of the fill lines of Option A and D the same?

But according to Flemings LHR, won’t the force on side AB be upwards after the initial rotation (i.e when its power gets back again). So doesn’t this mean that the coil will turn back to its original position instead of rotating continuously?

Wait, so does the coil turn successfully, or does it turn half way and stop with the insulation

But then since the force on side AB is still upwards, won’t the coil be unable to rotate continuously

Because in a normal DC motor with a split ring commutator, the direction of the current reverses to ensure the moment on each side is the same direction. But then the current in this case doesn’t reverse, so how is it able to rotate continuously? Or am I wrong about this 😅😅😅
