Explanation:
The magnetic force will act perpendicular to velocity at every instant ,path will be circle. Due to change in direction momentum will change but the total energy will remain same.
Answer:
➡️the magnetic field applies a force perpendicular to the velocity. Hence, the force can't do work on the particle. As a result, the particle can't change its kinetic energy. So it can not change the speed.
➡️The magnetic force will act perpendicular to velocity at every instant ,path will be circle. Due to change in direction momentum will change but the total energy will remain same.
➡️If a charged particle is projected perpendicular to a uniform magnetic field, then particle revolves in a circular path and its kinetic energy remains constant since there is no work done by magnetic force. Since a circular path direction of particle changes, so, momentum also changes.
➡️ the velocity remains samé
