An electron (me = 9.11 1031 kg) with velocity v = (2.50 106 m/s)i + (3.00 106 m/s)j moves through a uniform

An electron (me = 9.11 × 10−31 kg) with velocity v = (2.50 × 106 m/s)ˆi + (3.00 × 106 m/s)ˆj moves through a uniform magnetic field B = (0.20 T)ˆi − (0.15 T)ˆk. Calculate the (a) magnetic force exerted on the electron by the magnetic field and (b) the electron’s resulting acceleration. (c) How would your results in parts (a) and (b) be different if, instead, the particle had been a proton? Explain.
