Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

<Homework 4
Problem 23.54
A problem of practical interest is to make a beam of
electrons turn a 90° corner. This can be done with the
parallel-plate capacitor shown in (Figure 1). An electron
with kinetic energy 3.4x10-17 J enters through a small
hole in the bottom plate of the capacitor.
