Yes, I did it the same way, but I had a different result... thank you.
Did you multiply energy by 2? It should be 2.24
14 000ev = 1.60*10^{-19}*14 000 = 2.24*10^{-15}
Yes, we must multiplay it - but later, when we want to find v in last equation. What did you substitute for q and have you...
Homework Statement
Hello. I have an exam soon so I need to do many exercises. I have a problem with one. I need to get an acceleration of electrons in lamp which energy is 14 000 eV and magnetic induction is B = 5.5*10^(-5) T.
