Quizplus · Accepted Answer

The kinetic energy gained by an electron accelerating through a potential difference (V) is given by the formula KE = eV, where e is the charge of an electron. Substituting the given values, we get KE = (1.6 x 10^-19 C) x (5.0 x 10^3 V) = 8.0 x 10^-16 J. Therefore, the correct answer is option B.
