Detailed Solution

The universal law of gravitation states that every object having some mass attracts every other object having some mass with a force that is directly proportional to the product of the masses of the objects and inversely proportional to the distance between them. It can be given by:
$F = \frac{G M m}{r^{2}}$
Where, G is the universal gravitational constant having the value, 6.67 X 10^-11 Nm²/kg².
The Law of gravitation just explains the gravitational force, it does not explain why gravity exists or how the force is exerted between objects when they are not in contact. Therefore first three statements are correct. Since the gravitational force is always attractive in nature, we can say that the last statement is wrong.
