An electron moves in a circular path perpendicular to a magnetic field of magnitude 0.280 T. If the kinetic energy of the electron is 3.50 x 10-19 J, find the speed of the electron and the radius of the circular path.
(a) the speed of the electron
Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s
(b) the radius of the circular path
