Since the object is moving with a constant velocity on a frictionless surface, there’s no net force acting on it! According to Newton’s first law, an object in motion stays in motion with the same velocity unless acted upon by an external force.
So, the force required to keep it moving with the same velocity is:(b) 0 N
