Explanation:
The step by step calculation can be found in the attachment below. Thank you.
Answer:
10,000 eV
Explanation:
According to the law of conservation of energy, the kinetic energy gained by the electron is equal to its change in electric potential energy:

where:
K is the kinetic energy of the electron
is the magnitude of the charge of the electron
is the potential difference through which the electron has been accelerated
For this electron in the TV, we have

Therefore, the kinetic energy of the electron in electronvolts is
