  • question_answer
    Assertion (A): Gauss theorem is not applicable in magnetism.
    Reason (R): Magnetic monopole does not exist.

    A) Both A and R are true and R is the correct explanation of A

    B) Both A and R are true but R is NOT the correct explanation of A

    C) A is true but R is false

    D) A is false and R is true

    Correct Answer: A

    Solution :

    Option [a] is correct.
    Explanation: Gauss's theorem of magnetism is different from that for electrostatics because electric charges may not exist in pair but magnetic poles always exist in pair. So assertion is true.
    Magnetic monopole does not exist. Magnetic poles always exist in pair. So reason is also true and reason clearly explains the assertion.
