The correct answer is C III.
To determine which picture shows the greatest gravitational force, we need to understand the concept of gravitational force and how it relates to the mass and distance between objects.
Gravitational force is the attractive force between two objects due to their mass. According to Newton's law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
In this case, we have pictures of objects with different masses placed at different distances apart. To compare their gravitational forces, we need to consider both the mass and the distance.
Let's analyze the pictures:
Picture I: This picture shows two objects with a mass of 10g (grams) each. However, the distance between them is not mentioned. So, we cannot determine the gravitational force just by looking at picture I.
Picture II: This picture also shows two objects with a mass of 10g each. The distance between them is mentioned as well, but for the purpose of this explanation, let's assume the distance is the same as in picture I. Therefore, the gravitational force between the objects in picture II would be the same as in picture I.
Picture III: This picture shows two objects with a mass of 2g each. However, the distance between them is not mentioned. So, we cannot determine the gravitational force just by looking at picture III.
Picture IV: This picture also shows two objects with a mass of 2g each. The distance between them is mentioned, but let's assume the distance is the same as in picture III. Therefore, the gravitational force between the objects in picture IV would be the same as in picture III.
Based on our analysis, we can conclude that neither picture I nor picture II has the greatest gravitational force since they have the same mass and distance. Similarly, neither picture III nor picture IV has the greatest gravitational force since they also have the same mass and distance.
Therefore, none of the given pictures show the greatest gravitational force.
To determine which picture shows the greatest gravitational force, we need to consider the masses of the objects involved. Looking at the pictures, all the objects have the same mass, which is indicated by the numbers written beside them (10 g and 2 g).
From the description, the objects are placed at different distances apart. However, the gravitational force between two objects depends on their masses and the distance between them.
Since all the objects have the same mass, the only factor affecting the gravitational force is the distance between them. The closer the objects are to each other, the stronger the gravitational force.
Comparing the distances between the objects in each picture, we can determine that the objects in Picture B (II) are closest to each other. Therefore, Picture B shows the greatest gravitational force.
So the answer is B) II.
