Question

which of the following property of a proton can change while it moves freely in a magnetic field​

Answer 1

Answer:

(C) velocity and (D) momentum

The force acting on the proton would change both velocity and momentum. If a charged particle's velocity is completely parallel to the magnetic field, the magnetic field will exert no force on the particle, and thus the velocity will remain constant.
