So let's start with the statement of this question.
00:04
Now it says that which of these statements are true concerning the newton's law of gravitation, right? so let's start with each of the statement one by one, right? so the first statement that we have, it says that the gravitational force, right, the gravitational force is an attractive force, right? so the short answer for this statement is true, right? the statement is true.
00:47
The gravitational force is an attractive force and how do we know about it is as per definition, right? cavatational force is the attractive force that is relatively directly proportional, right? it's directly related to the product of the masses of two objects and inversely proportion to the square of the distance between them, right? so it's an attractive force, right? it's very much clear from the formula and from the definition that grapation force is an attractive force that is present between two objects, right? so let's say that these are two objects.
01:23
This is ball a and this is ball b, right? and this is the distance d between them, right? so as per the definition of the gravitational force, right, there exists there exists an attractive force between them, right? that would compel them to come closer to one another, right? and this force is directly proportioned to the mass of the product of the masses of these balls and inversely proportion to the square of the distance between them, right? so the first statement is clear.
02:02
Now, the second statement is that the gravitational force, right, that is present between the earth and a person, right? between the earth and person is constant, right? so now the first part of this statement is fall, right? we know that the gravitational force is dependent on the distance that is between two objects, right? so in this scenario, we have the two objects that was the first one is earth and the other is the person, right? so it means that the gravitational force between the earth and a person cannot be constant, no matter how the high the person is above the surface of the earth...
