A charged particle is moving in a uniform magnetic field. Which of the following statements concerning the magnetic force exerted on the particle is false?
A) It increases the speed of the particle.
B) It does no work on the particle.
C) It changes the velocity of the particle.
D) It does not change the kinetic energy of the particle.
E) It can act only on a particle in motion.
The Attempt at a Solution
C isnt it? because when a charged particle is in a magnetic field the magnetic force forms two right angles which will cancel each other and velocity will stay constantM
