Question

The weight of an object depends on:
A. Mass of the object
B. Acceleration due to gravity
C. Both A and B
D. None of the above.

Answer 1

Hint: In this question we will understand that weight is a force acting on an object on the surface of a planet due to the gravitational force acting on it. The weight of the object depends on the mass of the object and the acceleration due to gravity and it varies from one planet or astronomical object to another.

Formula used:
$W = mg$
Where,
$W$ is the weight of an object,
$m$ is the mass and
$g$ is the acceleration due to gravity.

Complete answer:
As we know that the weight of an object is the product of mass and gravity so from this, we can say that weight depends upon the mass of the object and the acceleration due to gravity. Let’s discuss in depth.
Basically, the weight is the amount that something weighs.
It is defined as the force that acts at all times on the objects near to the earth’s surface.
In the field of science and engineering, the weight of an object is related to the force acting on that object, either due to gravity or due to a reaction force that holds it in a place.
In simple terms, it is the force with which a body is pulled towards the earth.
Therefore, weight is the measure of the heaviness of an object.
Hence, the correct option is C.

Note:
The acceleration due to the gravity of a planet of mass M and radius R is given by,
$g = \dfrac{{GM}}{{{R^2}}}$
Where,
$G$ is the gravitational constant,
$M$ is the mass of the planet and
$R$ is the radius of the planet.
The SI unit of weight is the same as of force i.e., $N$ and while the SI unit of mass is $kg$ .
