Question
A cube of mass m1 = 7.7 kg is sitting on top of another cube of the same size and mass m2 = 0.6 kg while they are both in free-fall. Ignoring any air resistance, what is the magnitude of the normal force with which the bottom cube is acting on the top cube?
for this question. I used FN=mg. I multiplied 7.7 x9.8 to get 75N but I got it wrong.
Please help

They are equal to each other so zero force
