One can define an alpha-volt $(\alpha-V)$ to be the energy acquired by an $\alpha$-particle when it is accelerated by a potential of $1 \,V$. For this problem,you may take a proton to be $2000$ times heavier than an electron. Then,
- A$1 \alpha-V = 1 \,eV / 4000$
- B$1 \alpha-V = 2 \,eV$
- C$1 \alpha-V = 8000 \,eV$
- D$1 \alpha-V = 1 \,eV$
