Explanation / Answer

force on a charge particle=charge *electric field

as here charge is positive, force will be along the same direction as the electric field i.e. the +ve x direction.

part a:

acceleration=force/mass

=charge*electric field/mass

=q*E/m

=4.7303*10^5 m/s^2

part b:

displacement=initial speed*time+0.5*acceleration*time^2

=0+0.5*4.7303*10^5*2.9^2

=1.9891*10^6 m
