A charged particle enters a magnetic field with velocity v at an angle θ with the field and experiences a magnetic force. The kinetic energy of the particle |
becomes maximum if θ = 90° becomes maximum if θ = 0° becomes minimum if θ = 180° is not affected by magnetic force |
is not affected by magnetic force |
The correct answer is Option (4) → is not affected by magnetic force The magnetic force acting on a charged particle is always perpendicular to its velocity. Hence, the force cannot do work on the particle and the kinetic energy of the particle remains unchanged. Answer: The kinetic energy of the particle remains constant. |
