Gravitational Force Nature
The question asks to identify the correct statement regarding gravitational force.
Analyzing Gravitational Force Properties
Let's examine each statement:
-
Statement 1: It depends on the medium between the objects.
This is incorrect. Gravitational force acts universally and does not depend on the medium separating the masses. For instance, the gravitational pull between Earth and the Moon is not altered by the presence of air or vacuum.
-
Statement 2: It depends on the charge of the objects.
This is incorrect. Gravitational force is dependent on the mass of the objects, not their electric charge. Electric force depends on charge, but gravitational force does not.
-
Statement 3: It can be both attractive and repulsive.
This is incorrect. Unlike electric or magnetic forces, gravitational force only exerts an attraction between objects with mass. There is no known repulsive gravitational force.
-
Statement 4: It is always attractive in nature.
This is correct. The fundamental characteristic of gravitational force, as described by Newton's Law of Universal Gravitation (F = G \frac{m_1 m_2}{r^2}), is that it always pulls objects towards each other. The force is always positive, indicating attraction.
Conclusion on Gravitational Force
Based on the analysis, the only correct statement describing gravitational force is that it is always attractive.
Important Questions from Gravitation
Which one of the following statement is true for the relation, \(F= \frac{{G{m_1}{m_2}}}{{{r^2}}}\) ?
(All symbols have their usual meanings)The free-fall acceleration g increases as one proceeds, at sea level, from the equator toward either pole. The reason is
A planet has a mass M 1and radius R 1. The value of acceleration due to gravity on its surface is g 1. There is another planet 2, whose mass and radius both are two times that of the first planet. Which one of the following is the acceleration due to gravity on the surface of planet 2?
Two bodies of mass M each are placed R distance apart. In another system, two bodies of mass 2M each are placed R/2 distance apart. If F be the gravitational force between the bodies in the first system, then the gravitational force between the bodies in the second system will be
Suppose the force of gravitation between two bodies of equal masses is F. If each mass is doubled keeping the distance of separation between them unchanged, the force would become
