In a television set, electrons are accelerated from rest through a potential difference of 19 kV. The electrons then pass through a 0.29 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. Here are my thoughts so far.... this is all i know.... B=F/(qv) B=.29 19kV=19000 V I need to find the velocity of the electron to solve for F, the only problem is..... I HAVE NO IDEA HOW TO RELATE POTENTIAL DIFFERENCE TO VELOCITY! please help. THANKS.
