In a television set, electrons are accelerated from rest through a potential difference of 17 kV. The electrons then pass through a 0.30 T magnetic field that deflects them to the appropriate spot on the screen. Find the magnitude of the maximum magnetic force that an electron can experience.
Force = qvBsin(theta)
B = Force/(charge x velocity)
The Attempt at a Solution
Well i am given electrons, i know their mass (m) and charge (q). I am also told that the electron starts from rest (0 m/s) and passes through a potential difference of 17,000 Volts. Then, the electrons pass through a .30 Tesla magnetic field. I don't think i can use equation 1 because i don't know v or sin(theta) and i don't think i can use equation 2 because i don't know the velocity. I would imagine that i need to find a way to tie the potential difference into one of the above equations so i looked at a formula sheet. i just don't see anything that could tie the 2 concepts together. what am i overlooking on this one?
