Consider the following statements: All the objects in the universe ...
Explanation:
The correct statements are 1 and 3 only.
Statement 1: All the objects in the universe attract each other with a force of gravitational attraction.
This statement is correct. According to Newton's law of universal gravitation, every object with mass attracts every other object with mass. This force of attraction is known as the gravitational force. It is a fundamental force of nature that acts between all objects in the universe, regardless of their size or distance from each other.
Statement 2: The force of gravitational attraction is dependent on the medium between the two bodies.
This statement is incorrect. The force of gravitational attraction does not depend on the medium between two bodies. It solely depends on the masses of the objects and the distance between them. In a vacuum, where there is no medium, the force of gravitational attraction still acts between objects. The presence or absence of a medium does not affect the gravitational force.
Statement 3: Scientists have yet to discover a carrier particle associated with the gravitational force.
This statement is correct. In particle physics, every fundamental force is associated with a carrier particle. For example, the electromagnetic force is carried by photons, and the strong force is carried by gluons. However, scientists have not been able to identify a specific particle that carries the gravitational force. This is one of the open questions in physics, and the search for a particle associated with gravity is ongoing.
Conclusion:
In conclusion, statement 1 and 3 are correct. All objects in the universe attract each other with a force of gravitational attraction, and scientists have yet to discover a carrier particle associated with the gravitational force. However, statement 2 is incorrect as the force of gravitational attraction is not dependent on the medium between two bodies.
