NEET Physics Magnetic Effects of Current / करंट का चुंबकीय प्रभाव NEET PYQ-Magnetic Effects Of Current

  • question_answer
    A particle mass m, charge Q and kinetic energy T enters a transverse uniform magnetic field of induction \[\overrightarrow{B}\]. After 3s the kinetic energy of the particle will be                   [AIPMPT (S) 2008]

    A)  3T      

    B)      2T

    C)  T        

    D)  AT

    Correct Answer: C

    Solution :

    [c] After passing through a magnetic field, the magnitude of its mass and velocity of the particle remain same, so its energy does not change, i.e., kinetic energy will remain T.
