Weight is a fundamental concept in physics that refers to the force exerted on an object due to gravity. Here is a detailed explanation of the given statement:
Weight is the force experienced by an object due to the gravitational pull of the Earth or any other celestial body. It is a vector quantity because it has both magnitude and direction. The direction of the weight vector is always towards the center of the celestial body.
-
- Weight is a vector quantity because it has both magnitude and direction. The magnitude of weight is equal to the product of the mass of the object and the acceleration due to gravity. The direction of weight is always towards the center of the celestial body.
-
- Weight is directly proportional to the mass of the object. In interplanetary space, where the gravitational field is weak or negligible, the weight of a body would be much less compared to its weight on Earth. Therefore, the weight of a body in interplanetary space is not maximum.
-
- As bodies go up in the Earth's atmosphere, they move farther away from the center of the Earth. The distance between the body and the center of the Earth increases, which leads to a decrease in the acceleration due to gravity. Consequently, the weight of the body decreases as it goes up, rather than increasing.
-
- The correct answer is not "D: None of these" because option A, which states that weight is a vector quantity, is correct.
Weight:
Weight is the force experienced by an object due to the gravitational pull of the Earth or any other celestial body. It is a vector quantity because it has both magnitude and direction. The direction of the weight vector is always towards the center of the celestial body.
Explanation of the given options:
-
A: Is a vector quantity:
- Weight is a vector quantity because it has both magnitude and direction. The magnitude of weight is equal to the product of the mass of the object and the acceleration due to gravity. The direction of weight is always towards the center of the celestial body.
-
B: Of a body in interplanetary space is maximum:
- Weight is directly proportional to the mass of the object. In interplanetary space, where the gravitational field is weak or negligible, the weight of a body would be much less compared to its weight on Earth. Therefore, the weight of a body in interplanetary space is not maximum.
-
C: Increases when the bodies go up:
- As bodies go up in the Earth's atmosphere, they move farther away from the center of the Earth. The distance between the body and the center of the Earth increases, which leads to a decrease in the acceleration due to gravity. Consequently, the weight of the body decreases as it goes up, rather than increasing.
-
D: None of these:
- The correct answer is not "D: None of these" because option A, which states that weight is a vector quantity, is correct.

Weight is a vector quantity because it has both magnitude and direction. It is the force experienced by an object due to gravity. The magnitude of weight is given by the formula W = mg, where m is the mass of the object and g is the acceleration due to gravity. The direction of weight is always towards the center of the Earth.
In the context of interplanetary space, the weight of a body is maximum when it is closest to a massive celestial object such as a planet or a star. This is because the force of gravity is stronger when the distance between the two objects is smaller. As the body moves away from the massive object, the force of gravity and hence the weight decreases.
When bodies go up, meaning when they move away from the Earth's surface, their weight decreases. This is because the gravitational force acting on the bodies decreases with increasing distance from the Earth. So, option C is incorrect.
Weight is a vector quantity and has both magnitude and direction. It is always directed towards the center of the Earth. Option A is correct.
In summary, weight is a vector quantity that represents the force experienced by an object due to gravity. It has both magnitude and direction, and its magnitude is given by W = mg. In interplanetary space, weight is maximum when a body is closest to a massive celestial object and decreases as the body moves away from it.
