Step-by-step explanation
From the question, we can see that the acceleration of the object varies inversely with the mass when a certain constant force acts on the object. We can express this as;

Therefore, when the mass is 3kg, the acceleration of the object is 10 /ms2.

Therefore, if the same force acts upon another object whose mass is 2 kg, the object's acceleration becomes.

Answer: 15 meters per seconds square.
