Electric and Magnetic Fields
a) An electron (initially at rest) is accelerated from the negative plate to a positive plate that is located 20 cm away. The voltage across the plates is 200 V. What is the velocity of the electron as it reaches the positive plate?
b) Now if the electron passes through a small hole in the positive plate (travelling right) and enters a magnetic field (B = 0.5 T) that is directed perpendicular to the direction of motion (pointing up), what would the magnetic force and direction on the electron?
Please show and explain as much work as possible. Thank you!

An electron is accelerated from rest across the gap of a capacitor (two parallel plates charged -Q and +Q respectively). A hole in the top plate allows the electron to emerge with a constant velocity of v = 71 m/s. If the gap between the plates is d = 0.47 m, what is the magnitude of the electric field between the plates?
