. An electron accelerates from rest through an electric field and into

. An electron accelerates from rest through an electric field and into a magnetic field travelling at a speed of 3 x 10 m/s as shown in the diagram below. The plates have a potential difference of 25 V, and the magnetic field has a magnitude of 0.50 T. (Remember: me = 9.11 x 10-31 kg and e = -1.6 10-1c.) (a) Calculate the magnitude and direction of the magnetic force on the electron. (b) Calculate the radius of the electron's circular path. +ve -ve electron I I
