Physics · Force on a moving charge in uniform magnetic and electric fields
Assertion A stationary charged particle in a magnetic field does not experience
Assertion A stationary charged particle in a magnetic field does not experience a force. Reason The force acting on a charged particle does not depend on velocity of the particle
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Assertion is incorrect but Reason is correct
Step-by-step solution
The magnetic force on a charged particle is given by F = q (v × B). For a stationary particle (v = 0), the force is zero, so the assertion is true. However, the force depends on the velocity (it is proportional to v), so the reason is false. Thus, the assertion is correct but the reason is incorrect.
