Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Definition of Electron Volt (eV)**: An electron volt (eV) is a unit of energy that is commonly used in the field of physics, particularly in the context of atomic and particle physics. 2. **Understanding the Concept**: The electron volt is defined as the amount of kinetic energy gained by an electron when it is accelerated through a potential difference of one volt. 3. **Setting Up the Scenario**: Consider two metal plates with a potential difference between them. One plate is at 0 volts (0V) and the other is at 1 volt (1V). An electron is ejected from the 0V plate and moves toward the 1V plate. ...
