Question

Assertion : The work done by magnetic force on a moving charged particle is zero.
Reason : The work done by magnetic force on a charged particle is zero as the force is always parallel to velocity of particle. .

• A. If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
• B. If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
• C. If the Assertion is correct but Reason is incorrect.
• D. If the Assertion is incorrect and Reason is correct.

Answer 1

Answer: (C)

Since the magnetic force is always perpendicular to the velocity of the charged particle so, work done is always zero.
