an electron in a TV picture tube is accelerated through a potential difference of 10 Kv before it hits the screen. What is the kinetic energy of the electron in electron volts when it hits the screen?
ok, so i know how to work this for Joules and i get: 1.6 x 10 ^-15 J. Now i am not so sure about converting this to eV, I looked up a conversion on the internet and found: 1 eV= 1.6 x 10^-19 J so is it correct to say that the answer is:
1.0 x 10 ^4 eV
any help is appreciated.
