Chapter 22, Problem 21P(choose chapter or problem)
Charged particles pass through a velocity selector with electric and magnetic fields at right angles to each other, as shown in Figure 22–32. If the electric field has a magnitude of 450 N/C and the magnetic field has a magnitude of 0.18 T, what speed must the particles have to pass through the selector undeflected?

ANSWER:
Step 1 of 2:-
Here, we have to calculate the speed of the particle for which it will pass through the selector undeflected.
The net force on the particle must be zero in order to keep it undeflected.
The electric force is in +ve direction and the magnetic force is in -ve y direction, which we found from the right hand screw rule.
