Doubt

1.there should be acceleration of particle in x direction due to electric field while having constant velocity in y direction

2.because there is velocity perpendicular to magnetic field there should be forced on particle in negative z direction (or in the screen)

But in solution there is no acceleration due to magnetic field can someone explain why?
