MCQ
Give the unit of work function.
- ✓Electron volt
- BJoule
- CHertz
- DWatt
✓
Answer
Correct option: A.
Electron volt
One electron volt is the kinetic energy gained by an electron when it is accelerated through a potential difference of $1$ volt.
Therefore, $1 \mathrm\ {eV}=1.602 \times 10^{-19}J$.
