(a) An electron moves through a uniform electric field E = (2.101 + 6.00) V/m and a uniform magnetic field B = 0.400k T. Determine the acceleration of the electron when it has a velocity v = 9.0 m/s. (Give each component in m/s.) ax = m/s ay m/s m/s az = = (b) What If? For the electron moving along the x-axis in the fields in part (a), what initial speed (in m/s) would result in the electron only experiencing an acceleration directed along the x-axis? m/s +
