## Homework Statement

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.

## Homework Equations

B=u0*I/2piR

I=Q/t

V/R=2pif

f=1/T

## 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?
