Question

the enegry of the charged particles moving in a uniform magnetic field does not change . because work done by the magnetic field on the charge is zero is this correct or not​

Answer 1

Correct..................

Answer 2

The force on a charged particle moving in a uniform magnetic field always acts in direction perpendicular to the direction of motion of the charge. As work done by magnetic field on the charge is zero, [W = FS cosq], so the energy of the charged particle does not change.
