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!
