Question

Three different identical charge particles are pictured in the same magnetic field which points into the screen (represented by blue X's). The particles are moving at the same speeds but in different directions, as indicated by the red arrows.
How do the particles rank. In terms of the force they experience due to their movements in the magnetic field greatest first?

• A. 1, 2, 3
• B. 1 and 2 tie, 3
• C. 3, 1 and 2 tie
• D. 3, 2, 1
• E. all tie,

Answer 1

Answer: (E)

all tie,

The equation for the force on a charged particle moving through a magnetic field IS $F=Bv\sin \theta$

where theta is the angle between the velocity direction and the direction of the magnetic field.If we look carefully at the directions here, we see that the velocity directions are all at ninety degrees to the magnetic field. All velocity directions are in the plane of the screen. The magnetic field direction is perpendicular to the screen.The force that all the charged particles experience is the same.

so correct Choice is option "E"
