Answer:
B. All forces acting on a body are balanced.
Explanation:
A body is said to be at equilibrium when all forces acting on the body are balanced.
In science, the forces acting on a body is said to be balanced when the following conditions are met;
The leftward force acting on the body is balanced by a rightward force.
The downward force acting on the body is balanced by a upward force.
Therefore, when all the forces acting on the body are added together as vectors, the
resultant force (the vector sum of all forces) would be 0N.
This ultimately implies that, when an object is at equilibrium, the net force (measured in Newton) acting on the object must be equal to zero.
Since we know, [tex] F = ma[/tex]
Where,
F represents force measured in Newton (N).
m represents mass measured in kilogram (kg).
a represents acceleration measured in meters per seconds squared (m/s²).
Thus, for an object to be at equilibrium; both the net force and acceleration of the object is zero.
