Which option is correct?

### Understanding Equilibrium in Physics

When a system is in equilibrium, the following conditions are possible:

- **It is not moving nor accelerating**: This option indicates that the system is at rest and remains in a state of static equilibrium.

- **It can be moving but not accelerating**: This describes a system in dynamic equilibrium, where it moves at a constant velocity without any change in speed or direction.

- **It is accelerating**: This option is incorrect for equilibrium, as acceleration indicates a change in velocity, suggesting that the forces are not balanced.

In summary, a system in equilibrium experiences no net force, meaning it either stays at rest or moves at a constant velocity.

Expert Solution
Step 1

Mathematically, Newton's second law of motion can be represented as,

F = ma, where F is the net force acting on a particle of mass m accelerating with an acceleration a.
