2. An electron accelerates from rest through an electric field and into a magnetic field as shown in the diagram below. The plates have a potential difference of 85 V and the magnetic field has a magnitude of 0.75 T. (Remember: m = 9.1 x 10 kg and e = 1.6 x 10 "C.) (a) Calculate the initial speed of the electron upon entering the magnetic field. (b) Calculate the magnitude and direction of the magnetic force on the electron. (c) Calculate the radius of the electron's circular path. -ve +ve electron
