A section of an advertising sign consists of a long tube filled with neon gas having electrodes inside at both ends. A uniform electric field of 20 kN/C is set up between the electrodes, and neon ions accelerate along the length of the tube. Given that the ions each have a mass of 3.35 X 10^-26 kg and are singly ionized, determine their acceleration.

An electric field exerts a force on a charged particle according to the magnitude of the charge.
In this case, since your field is 20KN/C, the force on a singly charged ion is F=e*20KN/C where e is the elementary charge constant. Look in the constants section of your physics book for the value. Once you have this force, it's a matter of simple Newton's law F=ma to find the acceleration. They gave you the mass of the ion and you just found the force acting on it.
