Question

When charge particle enter perpendicular to magnetic field, the:​

Answer 1

Answer:

When charge particle enters in amagnetic field perpendicularly, then the magnitude of its velocity remains constant, but direction changes, so its energy (scalar quantity) remains constant, but its momentum (vector quantity) changes.

Answer 2

Answer: Hope it helps you :)

Explanation:

As the charged particle enters perpendicular to the magnetic field, the force will act perpendicular to the velocity. Thus the particle starts moving in the circular path. As force and displacement are perpendiculars the work done will be zero and kinetic energy will not change.
