Calculate the velocity of an electron with 3 eV energy. This electron is accelerated by a constant field of 10 V/cm (parallel to the electron velocity) for 0.1 cm. What is the new electron velocity?

My other problem is the unit for the electric field . it bothers me: V/cm usually it is N/C

2. Relevant equations

.5*m*v^2

Please can i have some suggestions?

3. The attempt at a solution

3eV=3 x 1.6E-19=4.8E-19 joules=1/2 mv^2, so v^2=4.8E-19/4.5E-31=1E12

so v=10^6 metres/sec.
