I have since deduced the radius, and indeed it was trivial. If you are interested, in calculating the required magnetic field of this square magnet to produce such a curve in a protons path through the magnetic field, the radius is simply the side length of one side of the square.

Homework Statement This is for a practice question on an exam: I am able to finish the problem, if I could figure out how to find the radius of this arc the proton makes. Homework Equations I have nothing. The Attempt at a Solution I have tried arc length equations and just integrating the...

There are 4A remaining 2A remain So N must have 2A, but I am still confused about M. I would think it to have 2A as well? Working backwards from the battery was something I did not think about. But since 1A comes back to the battery from the first square, an unknown amount leaves M, and then...

Homework Statement Find currents through M and N Homework Equations Current out must be current in. The Attempt at a Solution I think that it is simply 3 parallels running with 5A of current. So, M is in series with the 2A current thus also has 2A of current. Would N also be in series with...

Ah! Thank you for your help, your answer was correct (I double checked using a program at our physics lab). :smile:

Homework Statement List the order of brightness of each bulb (while the switch is open) assuming the bulbs are all of the same resistance. Homework Equations Ohm's Law: Change in voltage = current divided by resistance The Attempt at a Solution I know that bulbs A,C,D,F are all equal in...

Hello! I thought this would be the best place to discuss and ask physics problems, rather than pay for a tutor. College in America isn't free after all...
