centripetal force = magnetic force
m V^2/R = e V B, so
B = (m/e)*(V/R)
m and e are the electron mass and charge
electron acceleration = V^2/R
m V^2/R = e V B, so
B = (m/e)*(V/R)
m and e are the electron mass and charge
electron acceleration = V^2/R

You forgot to include the units for speed. 6*10^-6 is very slow if you are talking about m/s. Are you sure you gor the exponent right?
