Consider the following statements and select the incorrect statement.a...
Incorrect Statement Explanation:
The incorrect statement is option D: "There is no change in the energy of a charged particle moving in a magnetic field although a magnetic force is acting on it."
Explanation:
Energy Change in a Magnetic Field:
- When a charged particle moves in a magnetic field, it experiences a magnetic force perpendicular to its velocity. This force causes the particle to move in a circular path.
- As the particle moves in a circle, its direction of motion constantly changes, leading to a change in its kinetic energy.
- The work done by the magnetic force results in a centripetal acceleration, and the particle's kinetic energy remains constant.
Energy Conservation:
- Although the kinetic energy of the charged particle remains constant in a magnetic field, there is a conversion between kinetic energy and potential energy.
- The particle's kinetic energy changes into potential energy as it moves against the magnetic force in a circular path. This potential energy is then converted back into kinetic energy as the particle moves along the circular path.
- Therefore, there is a continuous interchange between kinetic and potential energy, even though the total energy of the particle remains constant.
Conclusion:
- In summary, the statement that there is no change in the energy of a charged particle moving in a magnetic field is incorrect. The energy of the particle undergoes constant conversion between kinetic and potential energy as it moves in a circular path under the influence of a magnetic force.
