An electron entering Thomson’s e/m apparatus has an initial velocity (in horizontal direction only) of 4.0 x 106 m/s. In the lab is a permanent horseshoe magnet of strength 12 mT, which you would like to use. (a) What electric fi eld will you need in order to produce zero defl ection of the electrons as they travel through the apparatus? (b) The length of nonzero E and B fi elds is 2.0 cm.
