Question: a Repeat Exercise 4 but find the speed by using

(a) Repeat Exercise 4, but find the speed by using energy methods. Find the direction in which the electron is moving by considering electric potential energy changes.
In exercise
An electron is accelerated by a uniform electric field (1000 V/m) pointing vertically upward. Use Newton’s laws to determine the electron’s velocity after it moves 0.10 cm from rest.
(b) Does the electron gain or lose potential energy?
