If the same net force is applied to a 7 kg object and a 21 kg object, then

the 21 kg object accelerates three times faster than the 7 kg object.

the 7 kg object accelerates three times faster than the 21 kg object.

both objects accelerate at the same rate because the force is the same.

neither object will accelerate because there is a net force on the objects
