If a force gives a 2kg object an acceleration of 1.6 m/s2, what acceleration does this same force give to an 8kg object?

The force (on both masses) is
F = M*a = (2 kg)*(1.6 m/s^2) = 3.2 N
If the same force acts upon 8 kg (which four times the original mass), you get 1/4 the original acceleration. That would be 0.4 m/s^2.
3.2 = 8.0 * 0.4 Newtons 
if a gives a force 2kg object an acceleration 1.6,/s2 what does the smae force give to an object of 4kg
