Transcribed Image Text:

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 12 V, and the magnetic field has a magnitude of 0.30 T. (Remember: m₂ = 9.1*10³¹ kg and e = 1.6*10-¹⁹ C.) +ve -ve electron (a) Calculate the initial speed of the electron upon entering the magnetic field. I (b) Calculate the magnitude of the magnetic force on the electron. (c) Calculate the radius of the electron's circular path.
