Application +4 | -1

A free alpha particle and a free proton are separated by distance of

10^{-10} \mathrm{~m}

and are released. The kinetic energy of alpha particle when at infinite separation is

View answer and explanation

Correct option: B

9.2 \times 10^{-19} \mathrm{~J}

Option B (

9.2 \times 10^{-19} \mathrm{~J}

) is correct because it correctly calculates the kinetic energy of the alpha particle at infinite separation using conservation of energy and momentum.
