Answer:
10,000 eV
Explanation:
Due to the law of conservation of energy, the kinetic energy of the electron at the end of its path is equal to its initial electric potential energy, given by:
[tex]U=q\Delta V[/tex]
where
q is the electron charge
[tex]\Delta V[/tex] is the potential difference
Here we have:
[tex]q=1 e[/tex] is the electron's charged
[tex]\Delta V=10 kV=10,000 V[/tex] is the potential difference
Substituting into the formula, we have
[tex]U=(1e)(10,000 V)=10,000 eV[/tex]
