Question

Two equal charges enter a magnetic field oriented along the positive z-axis. The particles are initially at the origin. Charge A has a velocity = v0 + v0 + v0 and charge B has a velocity = 2v0 + + . In both cases the path of the motion will be a helix. What will be the difference in the patterns of motion?
Answer







The helix for B will have same-size circles as A, but spread further apart.








The helix for B will have wider circles closer to each other.








The helix for B will have wider circles spread further apart.








The helix for B will have same-size circles as A, but grouped closer to each other.








Both helixes will look the same.

Explanation / Answer

The difference in the patterns of motion is the helix for B will have wider circles spread further apart.This is because the speed of charge B is less than charge A.
