1. a** How much work is done if an electron is moved through a potential difference of 1 V? (The charge on an electron is −1.6×10−19 C.)
2. b** Physicists express this amount of work done as one electronvolt, eV. Calculate the electronvolts equivalent of
- i** 6.4×10−19 J.
- ii** 3.2×10−13 J.
- iii** 2×10−15 J.
3. c** Calculate the Joules equivalent of
- i** 3 eV.
- ii** 200 keV.
- iii** 7.4 M eV.
