If electrons are accelerated from rest in an electron gun by sending them through a potential difference of 11.0 kV, what is the resulting kinetic energy of each electron?

Question

Quizplus · Accepted Answer

The kinetic energy gained by an electron accelerated through a potential difference V is given by the equation KE = eV, where e is the charge of the electron (1.6 × 10⁻¹⁹ C). For a potential difference of 11.0 kV (11,000 V), KE = 1.6 × 10⁻¹⁹ C × 11,000 V = 1.76 × 10⁻¹⁵ J.
