{'magnetic forces': [0, 0, 0, 1], 'gravitational force': [0, 0, 0, 6], 'short range forces': [0, 0, 0, 1], 'long range force': [0, 0, 0, 1], 'electric': [0, 0, 0, 1], 'difference': [1, 3, 4, 8]}

Option 1 states that the gravitational force is stronger than the electric and magnetic forces. This is incorrect. In reality, the gravitational force is the weakest of the four fundamental forces in nature. The electromagnetic force, which includes both electric and magnetic forces, is much stronger.

Option 2 correctly states that the gravitational force is attractive only, while the electric and magnetic forces can be both attractive and repulsive. This is because charges can have the same or opposite signs, resulting in both attractive and repulsive forces between them. In contrast, masses that interact gravitationally always attract each other.

Option 3 is incorrect as it states that the gravitational force has a very short range. In reality, the gravitational force has an infinite range, meaning it can act over large distances.

Option 4 correctly states that the gravitational force is a long-range force, while the electric and magnetic forces are short range forces. The range of the electric and magnetic forces is limited to the distance between the charged or magnetized objects. If the objects are separated by a significant distance, these forces become negligible.

In conclusion, option 2 is the correct statement as it accurately describes the differences between the gravitational force and the electric and magnetic forces.
