What is the potential difference responsible for the acceleration of the electron? $\left( h = 6.626 \times 10 - 34 \mathrm {~J} \cdot \mathrm { s } , m _ { \text {electron } } = 9.11 \times 10 - 31 \mathrm {~kg} , e = 1.6*10- 19 \mathrm { C } \right)$
A) $2.5 \times 10 ^ { - 6 } \mathrm {~V}$
B) $1.7 \times 10 ^ { - 6 } \mathrm {~V}$
C) $2.2 \times 10 ^ { - 6 } \mathrm {~V}$
D) $1.9 \times 10 ^ { - 6 } \mathrm {~V}$
