An object of mass 2 kg is sliding with a constant velocity of 4 m/s on a frictionless horizontal table. What is the net force required to keep the object moving with the same velocity?

Answer: A. 0 N

Explanation: According to Newton's First Law of Motion (Law of Inertia), an object will continue to move at a constant velocity unless acted upon by an external unbalanced force. Since the table is frictionless and the velocity remains constant, the net external force required is exactly 0 Newtons.
