Are you saying that if you stick with your original choice then you win 50% of the time?

I think we had a similar thread a couple of years ago. It might be worth searching for it. I don't use hand rules, but remember the...

... because the horizontal component comprises two divergent integrals. Making the limit configuration fundamentally unphysical.

If a veridical paradox were not a paradox, would that itself be a veridical paradox?

... for example, in electrodynamics the field is everything. Griffiths uses this idea extensively. If two fields/forces on a particle...

A point particle also cannot have internal forces, so zero net force is equivalent to no forces in this context. Deleting that context...

Why did you delete the second half of the sentence that you quoted? Why the reference to subjective experience? We can measure...

I'll say it again more strongly. The only reliable way to handle an idealisation is as the limit of realistic versions. When there is...

The Coulomb integral giving the horizontal field does not converge (its value depends on how far the surface is extended to infinity)...

I am confused by this thread. Perhaps I misread something, Why try to replace a trivial Gauss's law solution by an ambiguous limit of...

Yes. In that case, there will be linear deceleration and rotational acceleration until the state of rolling without slipping is reached.

The cylinder is initially spinning in a clockwise direction. The frictional force on the cylinder is down the incline. This provides a...

Hi, I've often looked at this site for many interesting discussions, especially around math books. And often felt like I didn't have...

Exactly. Good point. It is the "filtering" action of the rule that makes the difference. With the rule, you know that if the remaining...
