Question

A charged particle moves horizontally into a region with a vertical magnetic field. The effect of the magnetic field is:

1,To leave the particle’s motion unchanged
2,To cause the particle to move in a curved path at constant speed
3,To cause the particle to slow down
4,To cause the particle to speed up

Answer 1

2....based on the principles of cyclotron

Answer 2

To cause the particles to move in a curved path at constant speed
