Electric Field Homework: Rank Protons by Acceleration

Click For Summary
In a uniform electric field, all protons experience the same magnitude of acceleration regardless of their initial velocities or directions. The acceleration is determined solely by the charge of the protons, their mass, and the strength of the electric field, which is constant. The discussion highlights confusion about whether the problem asks for ranking accelerations or velocities, but it clarifies that the accelerations will be identical for all protons. The participants conclude that the question may be a trick, as it emphasizes understanding the underlying physics rather than performing complex calculations. Ultimately, the key takeaway is that in a uniform electric field, the acceleration of charged particles is uniform across the board.

That's not a problem, it's a bonus and a clear result! You now now that the acceleration does not depend upon direction or speed or distance; It only depends on the charge, the mass, and the electric field. So what can you conclude for the different cases presented?
Their accelerations are the same?? That just doesn't seem like him. (professor)

Yes, the accelerations are all identical. It is the correct result for the question in the form it was given.

The question may seem like a trick, or perhaps it is incorrect due to a typo or otherwise, yet even so it got you to think about the physics of the situation.

Ok thanks gneill and berkeman. I guess you guys had said their accelerations were same in the beginning but it definitely helped figuring out why. I''ll talk to my professor tomorrow and I think it's actually due Tuesday so if there's something I'm missing I'll bring it up tomorrow?

Thanks!

That would be fine!
Thanks!
You're very welcome.
