.electric force must equal magnetic force acting on the protons!..........
Electron passing without deflection through a magnetic field of 0.6. T are balanced by a 4.5 * 10^3 N/C electric field. What is the speed of the moving protons?

To pass without deflection..electric force must equal magnetic force acting on the protons!....
electric force EQ = magnetic force BQV....
The Q's cancel out....leaving the speed V as equals to E÷B.......
V=( 4.5*10^3) ÷ 0.6. = 7500m/s
