Answer:
D. more mass is concentrated.
Step-by-step explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
Newton's law of universal gravitation states that the force of attraction (gravity) acting between the Earth and all physical objects is directly proportional to the Earth's mass, directly proportional to the physical object's mass and inversely proportional to the square of the distance separating the Earth's center and that physical object.
Center of gravity can be defined as the specific point where all of the weight of an object is concentrated.
Generally, all the objects found around the world all have a center of gravity.
Additionally, when an object is balanced so that a displacement lowers its center of gravity, the object is said to be in stable equilibrium.
The centre of gravity of a physical object is usually located where more mass is concentrated in the physical object or body.
However, the location of the centre of gravity is subject to change and as such doesn't always remain the same.
