SUMMARY

The discussion focuses on calculating the strength of a magnetic field for a 10nC, 1µg particle using the equations f = mv²/r and F = qvb. A participant highlights the importance of using proper SI units to avoid errors in calculations. The magnetic field strength calculated was 78 T, which is noted as excessively high, indicating a potential miscalculation due to unit conversion issues.

Homework Statement



A 10nC, 1µg particle is fired into a magnetic field as shown. Distances are in millimeters, time is in seconds. What is the strength of the field? (See my picture for additional information and my worked solution)


Homework Equations


f= mv^2 /r F(from B field) = qvb


The Attempt at a Solution


see picture for my work. I don't see what I am doing wrong.

Hello Erwin,
Wow, you sure have a wide screen. Doesn't prevent you from falling into the trap of forgetting to use proper units. Your expression for B is quite correct. Convert one of the factors to SI units and you are in business.

Hint: 78 T is incredibly huge for a magnetic field strength.
