(a) An electron moves through a uniform electric field E = (2.30î + 4.90j) V/m and a uniform magnetic field B = 0.400k T. Determine the acceleration of the electron when it has a velocity v = 11.0î m/s. (Give each component in m/s².) m/s2 m/s? a, = m/s2 (b) What If? For the electron moving along the x-axis in the fields in part (a), what speed (in m/s) would result in the electron also experiencing an acceleration directed along the x-axis? m/s
