Aproton and an alpha particle (helium nucleus consisting of two protons and two neutrons) are accelerated from rest across the same potential difference. assume the proton mass and the neutron mass are roughly the same and neglect any relativistic effect. compared to the final speed of the proton, the final speed of the alpha particle is? 1. less by a factor of 22. less by a factor of √ 23. less by a factor of 44. greater by a factor of 25. the same

option B

Explanation:

we know,

change in energy is equal to

proton mass and the neutron mass are roughly the same

so,

now,

we know,

mass of alpha particle is four times mass of the mass of proton. 

mα = 4 m_p

less by a factor of √2

Hence, the correct answer is option B

all of the answers are correct.

falsification is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.
