Electrons with kinetic energy K are injected into the space

Last updated: 7/23/2022

Electrons with kinetic energy K are injected into the space between two parallel conducting plates a distance d apart, connected to a battery of emf E. A magnetic field is applied to cause the electrons to travel in straight lines. c) Evaluate B if d = 5.0 mm, ε = 48 V, K = 71 eV.
