According to Newton's First Law of Motion, an object in motion will continue to move with a constant velocity unless acted upon by an external force.
Since the object is moving with a constant velocity of 5 m/s, we can conclude that the net force acting on the object is zero. This means that the forces acting on the object are balanced, resulting in no acceleration or change in velocity.
Therefore, the correct answer is b) The net force acting on the object is zero.

The answer to the question is option 'B': The net force acting on the object is zero.
Explanation:
When an object is moving with a constant velocity, it means that the object's speed and direction of motion are both constant. In order for an object to have a constant velocity, the net force acting on the object must be zero.
Newton's first law of motion, also known as the law of inertia, states that an object will remain at rest or move in a straight line with a constant velocity unless acted upon by an external force. In this case, the object is moving with a constant velocity of 5 m/s, which implies that there is no acceleration. Therefore, the net force acting on the object must be zero.
Key points:
- When an object is in motion with a constant velocity, it means that the forces acting on it are balanced.
- The net force is the vector sum of all the forces acting on an object.
- If the net force is zero, it means that the forces acting on the object are balanced, and there is no acceleration.
- In this case, the object has a mass of 2 kg and is moving with a constant velocity of 5 m/s. Since there is no change in the object's velocity, the net force acting on it must be zero.
- It is important to note that while the net force is zero, it does not mean that there are no forces acting on the object. There may be individual forces acting on the object, but their vector sum results in a net force of zero.
- The absence of a net force means that the object will continue to move with the same velocity unless acted upon by an external force.
