A particle of mass m\mathrm{m}, charge Q\mathrm{Q} and kinetic energy T\mathrm{T} enters a transverse uniform magnetic field of induction B⃗\vec{B}. After 3 seconds the kinetic energy of the particle will beA particle of mass m , charge Q and kinetic energy T enters a transverse uniform magnetic field of induction B . After

Options

  1. A4 T4 \mathrm{~T}
  2. B3 T3 \mathrm{~T}
  3. C2 T2 \mathrm{~T}
  4. DT\mathrm{T}

Correct answer

D. T\mathrm{T}

Step-by-step solution

Work done by magnetic field on charge particle is zero. Therefore its kinetic energy will be same i.e. T\mathrm{T} A particle of mass m , charge Q and kinetic energy T enters a transverse uniform magnetic field of induction B . After
