2. [1pt]
A charged particle moving at constant speed is entering a region of uniform magnetic field and follows the curved path shown in the diagram.


Consider each of the following changes to this situation and select the effect it will have, from the choices given below.

The initial velocity of the particle is halved.

The direction of the magnetic field is reversed.

The magnetic field strength is reduced to one third.

The particle is replaced by a neutral particle.


E.g., if change 1 causes B, change 2 causes A, change 3 causes C, and change 4 causes C, enter BACC. You have 15 tries.

This will alter only the direction of the magnetic force on the particle.

This will only increase the magnitude of the magnetic force on the particle.

This will only decrease the magnitude of the magnetic force on the particle.

This will alter both the magnitude and direction of the magnetic force on the particle.

This will not affect the magnetic force on the particle.
