Exam-style question
Try this first
Determine the specific charge of a helium nucleus (2 protons and 2 neutrons) with a total mass of 6.64 x 10^-27 kg and a total charge of +3.2 x 10^-19 C.
- A.4.81 x 10^8 C/kg
- B.4.80 x 10^7 C/kg
- C.4.82 x 10^8 C/kg
- D.4.83 x 10^8 C/kg
Model answer
What a good answer should say
- 4.81 x 10^8 C/kg
Explanation
Why this works
The specific charge of the helium nucleus is calculated as the total charge divided by the total mass, which is essential for understanding its behavior in electric fields.
