일반물리학 2 — Electric Fields: Problem 37

37 An electron is released from rest in a uniform electric field of magnitude $2.00 \times 10^4 \text{ N/C}$. (a) Calculate the acceleration of the electron. (Ignore gravitation.) (b) How much time does the electron take to reach $1.00\%$ of the speed of light? (c) How far does it travel in this time?
