Solve the all parts of following problem given below:
Problem: An electron with an initial speed of 6.00x10^5m/s is brought to rest by an electric field.
Part A: What was the potential difference that stopped the electron?
Part B: What was the initial kinetic energy of the electron, in electron volts?
I need help to find the initial kinetic energy of the electron, in electron volts.
