Hi,
My Question:
What is the velocity of a beam of electrons taht go undeflected and magnetic fields of magnitude 8.8 x 10^3 V/m and 3.5 x 10^.9 T, respectively? what is the radius of the electron orbit if the electric field is turned off?
My Work:
V= E/B
V=(8.8 x 10^3 V/m)/(3.5 x 10^.9 T)
V=2.51 x 10^-6 m/s
and for the radius
r=mv/qB
r=(9.11 X 10^-31 kg)(2.51 x 10^-6 m/s)/(1.6 x 10^-19 coul)(3.5 x 10^-3 T)
r= .004m
Are these correct
Thank You
