Homework Statement
As an electron moves through a region of space, its speed increases from 2.2e^6 m/s to 6.0e^6 m/s. The electric force is the only force acting on the electron.
a) Did the electron move to a higher potential or a lower potential?
b)Across what potential difference did the electron travel?
Homework Equations
well for part b, I'm not even sure what to use.
K = 1/2mv^2
U=q x V
The Attempt at a Solution
Well i know part a), the electron moves to a higher potential.
I really don't know how to solve this since the distance or time is not given. And I may be confused as to the difference between potential difference and electric potential. I don't know where to start!
