Suppose the mass of Object 1 is greater than that of Object 2 and that both objects are at rest until an explosion occurs.

The objects exert the same force on each other

Object 2 exerts more force than Object 1

Object 1 exerts more force than Object 2

Not enough information

The objects exert the same force on each other.

Explanation:

Let us suppose that the mass of object 1 is greater than that of object 2. Both objects are at rest until an explosion occurs. The first object exert an equal and opposite force on another object as per Newton's third law of motion. In this case, Newton's third law will be applicable. As a result, he objects exert the same force on each other. Hence, the correct option is (a).
