Gravitational force _____ on the nature of the medium between the charges. A. Depends B. Does not depend C. Sometimes depends D. None of these
Hint: Let us get some idea about charge. When matter is put in an electromagnetic field, it acquires an electric charge, which causes it to undergo a force. Positive and negative charges are the two forms of electric charge. Charges that are similar repel each other, while charges that are dissimilar attract each other.
Complete step-by-step solution: Gravity, also known as gravitation, is the fundamental force of attraction that acts between all matters in physics. It is the weakest known force in existence, and therefore has no bearing on the internal properties of ordinary matter. On the other hand, it governs the trajectories of bodies in the solar system and elsewhere in the universe, as well as the systems and evolution of stars, galaxies, and the whole cosmos, thanks to its vast scope and universal action. All bodies on Earth have a weight, or downward force of gravity, equal to their height, which is exerted on them by the Earth's mass. The acceleration that gravity imparts on freely falling particles is used to calculate gravity. The medium between two bodies has no effect on gravitational force. So option (b) correct.
Note: The gravitational constant is used in Newton's Law of Gravitation as a proportionality constant. Newton's Constant is another name for it. The gravitational constant has the same value anywhere in the universe. G is not the same as g, which denotes the acceleration due to gravity.
