Sagot :
Answer:
The speed of the proton is [tex]v =5.95\times 10^{5} m/s[/tex]
Explanation:
Energy, E = 1.85 keV
mass of proton, m = 1.67 x 10^-27 kg
Let the speed is v.
The kinetic energy is given by
[tex]K = 0.5m\times v^{2}\\\\1.85\times \1.6\times 10^{-16} = 0.5\times 1.67\times 10^{-27}\times v^{2}\\\\v =5.95\times 10^{5} m/s[/tex]
