1. The problem statement, all variables and given/known data A rather simplistic model of the hydrogen atom has a single electron revolving around a nuclear proton with an orbital radius of 5.40E-9 m at a speed of 5.00E+6 m/s. Determine the magnetic field at the proton due to the electron. 2. Relevant equations B=u0*I/2piR I=Q/t V/R=2pif f=1/T 3. The attempt at a solution I tried to do V/R to get the angular frequency, converted to frequency then period. Take the period and divide it by the charge of an electrons. After putting the current in the formula, I got 0.000873 T, but it's wrong... any suggestions?
