question

a particle of charge q and mass m is moving with velocity in the positive x-direction.

(a) it is subjected to a uniform magnetic field b directed along negative z-direction. explain briefly the trajectory it would describe.

(b) when the particle is subjected simultaneously to both the magnetic and electric fields directed along the z-axis and y-axis respectively, obtain the condition when the particle will go undeflected.
