A i electron initially at rest, is accelerated through a potential difference of 200 volt, so that it acquires a velocity
\( \mathrm{P} \) \( 8.4 \times 10^{6} \mathrm{n} / \mathrm{s} \). The value of \( \mathrm{e} / \mathrm{m} \) of electron will be

(a) \( 2.76 \times 10^{12} \mathrm{C} / \mathrm{kg} \)
(b) \( 1.76 \times 10^{11} \mathrm{C} / \mathrm{kg} \)
(c) \( 0.76 \times 10^{12} \mathrm{C} / \mathrm{kg} \)
(d) None of these
