According to Newton's second law, force is directly proportional to acceleration and inversely proportional to mass. Thus, F = ma can be rearranged as a = F/m. Using this equation with the given force and a 8-kg mass: a = (1.6 N) / (8 kg) = 0.2 m/s^2. Therefore, the acceleration of the 8-kg object is 0.2 m/s^2, which is option B.
