MCQ
1 electron volt = __________ J.
- A1.6 × 10-19
- B4.8 × 10-19
- C1.6 × 10-10
- D10
✓
Answer
- 1.6 × 10-19
Explanation:
1 electron volt is the amount of work done if an electron is passed through a potential difference of 1V. Therefore the work done = 1V × charge of an electron = 1.602 × 10-19 J. But it is a small quantity and hence we use kilo electron volt and mega electron volt in practical.
