Explanation:
- Assuming no friction present, the change in electrical potential energy, must be equal in magnitude, to the change in kinetic energy of the electron.
- The change in the electrical potential energy, can be expressed as follows:
- The change in kinetic energy, assuming that the electron started from rest, can be written as follows:
⇒
- From the equation above, replacing by ΔK and ΔU, we have:
- Solving for v:
