Question

A charged particle traveling at a given speed enters a uniform magnetic field. The velocity vector of the particle is perpendicular to the magnetic field. Which of the following particle properties will change while in the magnetic field?

a) Its speed

b) Its velocity

c) Its kinetic energy

d) All of the above

e) None of the above

Answer 1

Since charge particle is entering perpendicularly in magnetic field therefore it will move in a circular path and hence the velocity will change of charge particle.

Hence option (b) is correct.
