In free fall do all objects fall with the same acceleration? yes, objects fall at a rate of 9.8m/swith acceleration. For every second in free fall you must add 9.8m/s to get the acceleration of an object.
Things with zero charge would not fall no matter what their mass is. In fact, the falling rate would be proportional to q/m, where q is the charge and m is the mass. When you tie two objects, 1 and 2, with charges q1, q2, and m1, m2, the combined object will fall at a rate (q1+q2)/(m1+m2).
