Application +4 | -1

An electron and a proton are accelerated through a potential

V

. If

P_{\mathrm{e}}

and

P_{\mathrm{p}}

are their momentum, then

P_{\mathrm{P}}: P_{\mathrm{e}}

ratio is approximately equal to

View answer and explanation

Correct option: D

43: 1

Option D (43:1) is correct because the ratio of momenta is proportional to the square root of the mass ratio, which is approximately the square root of 1836, resulting in approximately 43:1.
