Compare the kinetic io1v1ru/zr f1ws1qa )energy gained by a pd x):vnoz,y:jf7,w ttroton $(q=+e)$ to the energy gained by an alpha particle $(q=+2e)$ accelerated by the same voltage $V$.
参考答案:
The proton would gain half
the kinetic energy as compared to the alpha particle. The alpha particle has twice the charge of
the proton, and so has twice the potential energy for the same voltage. Thus the alpha will have twice the kinetic
energy of the proton after acceleration.
