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

    A) 3T    

    B)                                        2T

    C) T                             

    D) AT

    Correct Answer: C

    Solution :

                    After passing through a magnetic field, the magnitude of its mass and velocity of the particle remain same, so its energy does not change, ie.,-kinetic energy will remain T.
