An electron initially at rest is accelerated through a potential difference of \( 200 \mathrm{~V} \), so that it acquires a velocity of \( 8.4 \times 10^{6} \mathrm{~ms}^{-1} \). The value of \( e / \mathrm{m} \) of electron is
(a) \( 2.76 \times 10^{12} \mathrm{C} \mathrm{kg}^{-1} \)
(b) \( 1.76 \times 10^{11} \mathrm{C} \mathrm{kg}^{-1} \)
- (c) \( 0.76 \times 10^{12} \mathrm{C} \mathrm{kg}^{-1} \)
(d) \( 2.76 \times 10^{11} \mathrm{C} \mathrm{kg}^{-1} \)
\( \mathrm{P} \)
