Question

The centre of gravity of an object is _ _ _ _ _ _ _ _ whether it is placed near the surface of the Earth or near the surface of the Moon
A). Same
B). Different
C). Depend on the situation
D). None

Answer 1

Hint: The term center of the gravity of an object is the point at which the weight is uniformly scattered and their sides are balanced.

Complete step by step solution:
The center of mass of a point on a physical body, which behaves like as the whole mass is reduced over there.
At any moment, the force acted on a body, it showed to act on the centre of the mass.
No matter when the gravitational force acts on them, it shows that it is acting on a particular point on that body.
It generally corresponds with the centre of mass. Earth being a larger planet than the moon, the gravitational force is more intense on Earth as compared to the moon.
The location of the centre of mass does not vary with the intensity of the force acting on that body.
Similarly, the center of the gravity does not vary with the intensity of the gravitational force acting on it.
So, the centre of the gravity on the Earth and the Moon will be the same.
So, the option (A) is correct.

Note: A center of the human gravity is changed as per different positions of the body. But for different objects it is fixed. We can find the center of gravity many ways. One of the methods, we add the moments of all the masses to each other.
